Abstract A collection of canvases caked in colorful arrangements of browns and grays competes for space alongside an extensive accumulation of soil samples, old lab equipment, and remnants of assorted research projects in the basement of the Gorbatschow Building of the Berlin University of Technology. Remains of an artistic field experiment conducted last summer, the canvases mark the Soil Protection Department's attempts to integrate artistic dimensions into the soil science curriculum at the university. Such cross-disciplinary activities are gaining recognition elsewhere, as scientists, artists, educators, and environmentalists are developing a visual vernacular for the outermost skin of the earth.

Why, when and in what context did soil science and art merge horizons? While incidental depictions of soil and geologic forms may be identified in virtually all major artistic genres, artwork explicitly dealing with soil and soil conservation issues is uniquely characteristic to the more recent environmental arts movement spanning over the last 50 years. Regarding the art-historical developments from the Land Art monuments of the 60s and 70s to more recent interdisciplinary remediation projects, it is important to distinguish between artworks that favor a symbolic, conceptual use of the “earth,” and those that more specifically make reference to “soil” as a geophysical, agronomic or ecological body. In this chapter, we introduce soil art as a subgenre of environmental art. We review the subject of soil throughout different historical developments of the environmental arts movement, look at several artists who have taken on soil as a fundamental focus of their artistic practice, and share some reflections on our own soil art experimentation at the TU- Berlin. Finally, we address the benefits and challenges of cross-disciplinary experimentation. It is our hope that a thoughtful combination of soil science and art will inspire new opportunities for collaborations within and beyond the soil science community.

1. Historical Roots

1.1 Earthworks and Land Art

A plein-air extension of minimalism, Land Art, like happenings, interventions, installations and performance art, celebrated a distinct break from traditional forms of art making, art appreciation, and art theory. Unlike landscape painting, nature photography, and outdoor sculpture parks, Land Art incorporated the landscape not merely as subject or setting for the artwork but as an integral 2 part of it. The Land Art movement is perhaps best known for “Earthworks,” such as Robert Smithson’s iconic in the Great Salt Lake in Utah (1970), Michael Heizer’s Double Negative, cut into the Mormon Mesa in Nevada (1970), or Robert Morris’ Observatory in the Netherlands (1977).

Many of the Land Artists also transported their perceptions of nature into museums and gallery spaces, isolating “earth” as an abstraction of the landscape. Prior to his herculean pursuits with bulldozers, Robert Smithson, for example, repeatedly framed simple arrangements of gravel, sand, salt and slate in mirrored corners of exhibition spaces and in wooden boxes on gallery floors. Smithson designated these minimalistic works with natural elements as “non-sites,” as opposed to actual sites in natural settings. Alongside Smithson’s Non-Site at the Dwan Gallery’s “Earthworks” exhibition in 1968, Robert Morris similarly exhibited a pile of soil and rock installed as a sculpture.

In various exhibitions, Richard Long laid out arrangements of stones in museum settings, bringing attention to the raw materiality of natural elements, in juxtaposition with the contrived architectural context of the exhibition space. Artist Alan Sonfist similarly addressed the materiality of exhibition spaces in his Atlanta Earth Wall and Macomb Wall of Earth (1965). Here, the artist brought attention to the natural history architectural space by covering the outer walls with rippled sculptural facades made out of core samples taken from nearby sites.

Many are also familiar with ’s New York Earth Room (1977). In this work, de Maria made reference to the lost natural history of New York by filling an entire gallery with 197 m3 of peat rich soil. Probably the most massive A-Horizon (uppermost layer of organic enriched soil) on the whole island of , the New York Earth Room allows the viewer to experience the raw, rich odor and texture of an isolated oasis in the middle of a concrete jungle, creating an eerie monument to pre-Columbian New York.

The definitive Land Art works were, however, embedded in the landscape. Far away from the white-walled safety of museums and gallery spaces, artists such as Michael Heizer, Richard Long, Robert Morris, Dennis Oppenheim, and Robert Smithson provoked new ways of interpreting art and experiencing the environment. Despite their groundbreaking contribution to art history, many of the monumental Land Art works often failed to acknowledge or protect the ecologies of the landscapes in which they were situated. When the state of California required artist team Christo and Jeanne-Claude to complete an environmental impact report for their 24 mile long Running Fence in 1976, attention shifted from the art world elite to a wider public discussion on the environment. While art critic Michael Auping (1983) commented on the negative ecological 3 repercussions of Land Art in his essay “Earth Art: A Study in Ecological Politics,” Allen Carlson (2002), professor of environmental aesthetics, even denounced some of the monumental earth works as being an “aesthetic affront to nature.”

As cultural attitudes about environmental responsibility gradually shifted, artists adjusted their practice as well, ushering in a new canon of ephemeral, site-specific, ecologically conscious art that addressed nature for nature’s sake, and not simply as a novelty of the art world. Appearing in the same year as the “Earthworks” Exhibition, Joseph Beuys’ Earth Telephone (1968), consisting of a real telephone, earth, wire and straw, may thus be interpreted as a symbol of communication between artist and audience but also between humankind and nature. Earth Telephone (Fig. 1) represented a telepathic call for action, inviting other artists to follow a subtler, more sustainable path. Artists such as Charles Simonds and Ana Mendieta (among others) answered the call by creating ephemeral, allegorical works with soil that linked personal myths of creation with “the earth” as a fertile, celestial body. Works such as Alan Sonfist’s Time Landscape (1965- 1978), a recreation of a pre-colonial biotope in Manhattan, and Newton and Helen Mayer Harrison’s installation of an endangered meadow on the roof of the national art museum in Bonn (1996-1998) marked a new direction for the Land Art movement. Fig. 1: Joseph Beuys, Earth Telephone, 1968.

1.2 Ecological Art

While Land Art can be traced back to a distinct period of postmodern artistic activity of the late 20th century, ecological art emerged as a critical response to Land Art around the same time period, and continues to thrive as a branch of contemporary art today. Ecological art addresses issues such as sustainable land use, natural processes, biodiversity, habitat conservation, and renewable resources. Two main approaches may be articulated here: artistic remediation that is primarily aesthetic and remediation that is also ecologically restorative. For example, Barbara Matilsky (1992 p. 56) makes a distinction between artists who have “proposed or created ecological artworks that provide solutions to the problems facing natural and urban ecosystems,” and artists who hone their

4 skills to attract attention or create awareness of environmental issues by “framing the problems through a variety of media…” Such a distinction becomes apparent with regard to artists working with soils.

In Robert Smithson's Pour series, the artist literally dumped truckloads of asphalt and glass and barrels full of glue and sulphur down the slopes of already contaminated strip mines for the pure aesthetic enjoyment of watching the clattering, gooey descent. In contrast, Alan Sonfist sought to ameliorate such conditions by pouring rings of humus rich soil onto industrial brownfields. The airborne seeds that landed within the Pool of Virgin Earth (1975) brought new life to industrial wastelands. In the Grass Grows and Seeds works by Hans Haacke (1970), the artist similarly placed mounds of fertile soil on rooftops and in gallery spaces to exhibit the physical and biological processes of change, renewal, and decay. In another example, artist-biologist Kathryn Miller developed a bold but humorous series of artistic recultivations by literally “bombing” brownfields with grenade-like sculptures of soil and seeds from native plants (Fig. 2). Miller’s Seed Bombs (1992-2001) and Subdivision (1992-2001) soil mounds bring attention to the ecological potential of forgotten urban and industrial spaces. Fig. 2: Kathryn Miller, Seed Bombs, 1992.

Another example is Paolo Barrile’s Message Earth (1961-2003). Well aware of the environmental art activities that had been going on in the United States, the Italian painter abandoned his formal painting career in the ’60s to launch an ambitious, long-term series of performances, installations and public interventions. His mission was to collect and redistribute soil samples from all over the world as a symbolic gesture of environmental and social health. With the help of hundreds of artists, schoolchildren, and friends, Barrile scattered fertile soils on urban squares and brownfields, taking a passionate stance against soil sealing and environmental degradation.

5 1.3 Artistic Remediation and Regional Transformation

Some ecological art goes beyond recultivating degraded sites to using more complex techniques of soil remediation. Mel Chin, for example, teamed up with agronomist Rufus Chaney in 1990 to test out bioreactors at the Pig’s Eye Landfill in Saint Paul, Minnesota. Revival Fields consisted of a circular fenced-in area of geometric plantings of control species and “hyperaccumulators.” These are plants with unique abilities to take up contaminants such as heavy metals from the soil. After several years of research and documentation, the unique phytoremediation (i.e., remediation facilitated by plants) project generated interest for further collaboration, and was repeated in several locations in Germany and the United States. As different targeted pollutants required different treatments, new species were tested, bred and “installed” according to conditions of each location.

The artist, Georg Dietzler, has similarly confronted soil contamination issues by instrumentalizing mycoremediation (i.e., remediation facilitated by fungi) as art. (Fig. 3) In works such as Self-Decomposing Laboratory (1999) and Moveable Oyster Mushroom Patch (1996-1997), Dietzler makes use of oyster mushrooms (Pleurotus ostreatus) to break down organic pollutants such as PCBs (polychlorinated biphenyls). The oyster mushroom’s unique ability to split chemical structures without absorbing toxins makes it an edible byproduct of waste management. Dietzler’s work exposes the power and beauty of bioremediation in the filigree mycelium of prized gourmet mushrooms.

Fig. 3: Georg Dietzler, Testing an Industrial Site - Völklinger Hütte, 1989. 6 The reality of remediation is, however, often a complex and costly endeavor for artists as well as environmental engineers and soil scientists. When entire regions are at stake, scientists and artists must reach for solutions that are both ecologically and economically viable. For example, the coal mining regions of the Ruhr Valley in Germany, or mid-Appalachia in the United States, offer ample opportunity for experimental remediation projects. The scarred landscapes have attracted both aesthetic and ameliorative approaches that unfold like a barren canvas, spread out over many states on which to paint a new future.

One of the greatest post-mining success stories was initiated in 1994 in Vintondale, Pennsylvania by historian T. Alan Comp, and a group of artists, scientists, planners and members of the surrounding community. The success of AMD&ART lies in its interdisciplinary commitment to nature. The group has fought abandoned mine drainage (AMD) with interdisciplinary art, engineering and community activism. They have restored habitats and ecosystem health through artfully designed passive water treatment systems. Initiated by the Carnegie Mellon Studio for Creative Inquiry, the Nine Mile Run Greenway Project represents a similar effort to restore and protect a watershed in nearby Pittsburg. The project has merged art and community involvement to confront environmental issues such as soil sealing, storm water management, habitat depletion, erosion and freshwater eutrophication.

2. Soil Art – Unearthing a Genre

It is not surprising that when we mention soil art, or talk about interdisciplinary collaborations between artists and soil scientists, a frequent response is an immediate association with “Earthworks.” While most of the early Land Art and Earthworks were mainly concerned with various perceptions of space, artistic context, and historical meanings of landscape, soil art, in contrast, deals with the geophysical materiality and biochemical processes of the earth. It addresses the pluralistic roles and functions of soil as habitat, growth medium for plants, substrate for architectural structures, archeological archives, as a diverse natural filtration system, and as the basis of cultural identity. It explores the aesthetics of soil (see chapter on “The Aesthetics of Dirt” in this volume) as a complex mineral and organic body, with infinite combinations of colors, textures, formations and interpretive meanings. In light of the historical frameworks described above, we define ”soil art” as art consciously and specifically about, in, or with soil as such or soil conservation issues – created by artists, scientists, educators or collaborative efforts thereof.

7 Furthermore, soil art comprises a wide range of artistic disciplines beyond painting and sculpture, to include installation, performance, photography, video and cinema, animation, landscape architecture, environmental remediation, and the Internet. As the field of soil science belongs to the environmental sciences, we identify soil art as a subfield of environmental art.

In addition to the artists and groups mentioned above, we will highlight the following four artists and their works as prominent examples in the advancement of soil art. These artists move beyond environmental art audiences and symbolic uses of “earth,” to offer creative new insight on soil classification, documentation, and evaluation methods. Following the artists’ profiles, we will go on to share two reflections of our experience at the TU-Berlin as practical examples for combining soil science and artistic practice. Partly supported by the German Soil Science Society and the Berlin University of Technology, the Department of Soil Protection has been investigating several approaches to “art-pedology” in recent years. Several student projects, field exercises and thesis papers have been carried out since 2002. Many other successful examples of soil science and art collaboration are documented on the soil arts website, www.soilarts.com (Toland and Wessolek 2006).

2.1 Marianne Greve – One Earth Altar

Upon entering the sun-drenched interior of the “One World Church,” the visitor’s gaze immediately falls on the imposing One Earth Altar (Fig. 4a and 4b). Framed by tree-lined windows in the back, the glass and metal structure merges the crucifix as symbolic framework with an archive of earth-narratives. Hamburg-based environmental and conceptual artist, Marianne Greve, was invited to create the altar as the centerpiece for the “One World Church,” which was erected in Schneverdingen as part of the Expo 2000. Based on the artist’s earlier idea for an earth library, the Altar is designed as a set of massive folding metal bookshelves in the shape of a triptych cross behind a simple glass altar. The “earth books” that fill the shelves consist of soil samples collected from all over the world, poured into Plexiglas cases with reference numbers etched on the beveled bindings that sparkle in the afternoon sunlight. Seven years after its inauguration, the project includes over 5,000 earth books on its shelves, with room for a total 7,000.

Soil is the basis of all life on the planet and rich with symbolic meaning that can be traced to religions and cultures from the beginnings of human history. Marianne Greve (2001) describes the idea behind the work: “Earth from many places on the globe lets us realize our common

8 dependence on this thin layer of weather-beaten stone, from which life takes its nutrition and in which it leaves its traces.... There are different worldviews but only one earth, which in its diversity and in conjunction with special places always proved fascinating to all people.”

The One Earth Altar thus brings together people of all kinds, cultures and faiths, from every corner of the earth, to truly fulfill its name and purpose. Each earth book is documented in a local information terminal and on-line database (http://www.eine-erde-altar.net) according to origin, donor, key word and shelf location. The reference numbers of each book are generated randomly, so that the soil generously donated from Ambassadors and world leaders such as the Dalai Lama may be located next to those of local families. Each book is filled with about a half liter of soil and stones, and is accompanied by a reference sheet documenting geographic coordinates, locality and donor’s name, geological, historical, political, spiritual, and emotional relevance, as well as soil color, texture, age, and other physical properties. The artist encourages personal stories to be delivered along with historical and geological information. Each soil sample carries a personal legacy of historical and cultural remembrance - family weddings, births and deaths, individual and collective milestones, memories and tragedies. As expansive and impressive as any collection of soil samples in a scientific institution, the One Earth Altar captures the natural and cultural diversity of the earth, offering real and virtual visitors alike a new perspective on experiencing and archiving soils. Readers are welcomed to go on-line and explore the international soil collection, or to donate their own personal sample to this unique soil classification project.

9 2.2 Daro Montag – Bioglyphs

Despite differences in established soil classification and mapping methods, soil profiles provide a common groundwork for identifying, analyzing and documenting the thousands of soil types of the earth. Soil profiles are for the most part similar in form – a simple vertical trench revealing the various soil horizons from the topmost layer of leaf litter, to the humus-rich topsoil and weathered subsoils, to the underlying parent material (a typical “A-B-C” profile). Similar to the binomial nomenclature (categorization of genus and species) of all living organisms, soil types may also be determined based on particular diagnostic characteristics such as horizon sequencing, color and aggregation. Accompanying standardized field analyses, soil profiles are often preserved for educational purposes with photographs, digital models, soil monoliths, and so-called lacquer profile “peels,” a method invented by Ehrhard Voigt in 1930 and further developed by Prof. Reinhold Tüxen, in which a mirror image of the profile wall is preserved onto a cloth or board with multiple applications of an adhesive mixture.

Artist Daro Montag has developed a technique of profile preservation with film that transcends established soil documentation procedures. Montag’s method exposes the essence of the pedogenetic microcosm in a biologically determined, artistic soil taxonomy. Rather than photographing the soil, Montag allows soil microorganisms to eat away, and in a sense develop exposed film buried vertically in the earth. Photographer Paul Kilsby (2001, p. 4) describes this as a process of creating “not images after nature but traces of nature – bioglyphs” (Fig. 5). As nematodes and a host of other soil organisms nibble their way along the gelatin-enriched surface of the film, swirling organic patterns of cyan, magenta and yellow are left in the infinitesimal wake of their sightless journeys. Montag’s Bioglyphs portray decay as fine art, shedding colorful new light on the dark, unusual world of the detritivores (the diverse group of organisms that feed on decomposing matter). In the words of the artist, bioglyphs are “composition by decomposition,” where “everything is in the process of becoming something else” (Montag 2001, p. 8).

Montag’s use of film also encourages us to revisit Walter Benjamin’s discussion on aura and authenticity in the developing process. In his essay, “The Work of Art in the Age of Mechanical Reproduction,” cultural critic, Walter Benjamin (1936), describes the challenges photography and film present to traditional practices and interpretations of art. The reproducible nature of film complicates the “aura” of works of art, in their authenticity, creation, ownership and presentation, as the “original work” is no longer distinguishable from its copies. Montag seems to rekindle this discussion by inventing a new technique for “developing” film. Rejecting film as a merely 10 replicative media, Montag rather uses film to set the stage for tiny miraculous performances of microbial activity. The originality and thus “aura” of the work lies in the method rather than an intended result. And in this case, the final product is not only dependent on the artist’s ingenuity, but also on various biological processes in a given soil ecosystem. While the resulting “bioglyph” may be reproduced in print form, the phenomenological capturing of the image preserves both the aura of the medium as well as the unfolding of pedogenetic events. Montag’s unusual use of film thus “does not portray objects or entities – it discloses events. It is not concerned with classification but with revelation” (Montag 2001, p. 8).

Soil is also to be seen here as Prima Materia, the primitive formless base of all matter (Montag 2007). It is a continuous cycling of mineral nutrients and biotic activity, an enigmatic universe that cannot be captured in a single photograph, monolith, lacquer peel or scientific field survey. Montag’s unconventional soil profiles, or bioglyphs, are a collaborative art with microorganisms - a creative, cross-species experiment that compliments and challenges accepted concepts of soil documentation and classification as well as traditional photography.

11 2.3 Betty Beier – Erdschollen Archive (Earth Print Archive)

Urban soils do not merely provide sites for new construction and infrastructure, but also determine the quality of human health, local climate, water supply, safe waste storage, plant and animal habitats, and in some developing countries, even provide the source of nutrition and food production for the urban population. Soil is the fundamental substrate common to all terrestrial locations – natural or humanly altered. The shift in focus of environmental art from remote and rural locations to urban centers may be compared with the relatively recent increase in urban ecological research. For example, the SUITMA (soils of urban, industrial, traffic, mining and military areas) working group, initiated in 2000 by Prof. Wolfgang Burkhardt and others, examines not only the impacts of contamination but also the ecological potentials of anthropogenic soils. Despite SUITMA’s progress, the classification and documentation of urban and industrial soils remains a major task. Although technosols (soils unnaturally brought to the surface, created, or substantially modified as part of an industrial or manufacturing process) have been just recently recognized in the World Reference Base for Soil Resources (Spaargaren 2005), the scope, heterogeneity and rapid growth of this urban soil group presents a significant need for future research.

In another soil-archiving project, artist Betty Beier has spent over ten years documenting technosols around the world. Concerned with the rising yearly loss of soil due to urban and industrial development, Beier explores the loss of landscape in the series Erdschollen Archive (Earth Print Archive). Although it is estimated that over 130 hectares of land are lost each year in Germany alone due to building and transportation projects, the German Federal Soil Protection Act (BBodSchG) does not even recognize soil sealing as an environmental impact (Wessolek 2008). Beier’s Erdschollen Archive documents the vanishing surfaces of her own country and beyond as “landscape” is transformed into urban and industrial sites via soil sealing.

Using a method similar to Voigt’s lacquer peel technique, described above, Beier’s Erdschollen are neither paintings in a traditional sense, nor lacquer profiles, but something in between. Rather than digging a vertical trench to reveal the hidden composition of humanly created soil horizons, Beier makes earth casts with plaster molds and acrylic resins in square meter aluminum frames laid out horizontally on the surface. Reminiscent of Mark Dion’s A Yard of Jungle (1992), in which the artist relocated one square yard of rainforest to the Museo de Arte Moderna during the Rio Earth Summit in 1992, Beier similarly extracts square meter samples of soil from various cultural and industrial landscapes. Here, as in Dion’s Yard of Jungle, the square meter as artistic framing 12 mechanism is used as an instrument of dislocation and a critical measurement of land use.

Working in such diverse places as the Xiaolangdi Dam in China, the Kárahnjúkar power plant in the Islandic highlands, and urban and mining areas in Germany, Beier’s work explores rugged and degraded anthropogenic soils and the histories held within them. The growing archive of over 60 Erdschollen, is also accompanied by soil samples, photographs, and drawings of each site, as well as notes about the natural history, culture and politics of the regions. Art historian, Jörg Katerndahl (2006, p. 5) writes: “By analyzing the surface, (Beier’s) work always reveals something from the underneath, the technical aspirations, the political background and the fates of the people affected.”

Tire tracks, windblown footprints, trickles of surface runoff, and even the reflections cast in murky puddles are all frozen as moments in time. (Fig. 6) Excavated and abstracted from the landscape, the Erdschollen appear as memoirs of a vanishing resource – landscape sealed in symbolism and acrylic rather than asphalt. Beier’s technolsolic portraits capture the rapidly changing face of the earth and challenge viewers to retrace the steps of industrial development, land allocation, and the importance and impermanence of site. In this sense, Beier develops Robert Smithson’s earlier concept of “non-sites,” by abstracting and isolating elements taken from the landscape and then using artistic methods to archive contemporary land use. The Erdschollen Archive and accompanying materials are documented on the website www.erdschollenarchiv.de

13 3.4 John Sturgeon – The “More Moor” Performances

Natural peats and bog soils are a result of organic matter accumulation under anaerobic conditions. The organic soil layers reveal the former conditions of plant communities and climate changes over relatively recent geological time. Organic soils were formerly a sink for nutrients, humic substances, and water until humans started using these soils for food and fuel production about 250 years ago. The fate of these wetlands and their organic soils has become a major environmental concern. Having been drained for agricultural production, their role in the landscape changed from a sink to a source of CO2 and N2O. To successfully restore and conserve peat and bog soils, it is important to protect their natural soil water and nutrient regimes. This becomes more and more difficult in a state of rapid global climate change.

One special quality of organic soils is that they are spongy and seem to float over the underlying groundwater, which can easily be tested by jogging across the surface. In fact, to truly experience the resilience of ten thousand years of accumulated organic matter, one must jump up and down in a bog. This is how we introduce students to the drained landscapes of Brandenburg. And this is exactly what John Sturgeon did as a segue to other performances and installations at the “More Moor” Symposium in 1992 in the nature conservation area of "Holler and Wittemoor," near Oldenburg, Germany. Sturgeon’s Falling Moor performance may be seen as a response to Joseph Beuys’ Bog Action (Eine Aktion im Moor) of 1971, in which the artist ran, bathed and swam through a bog in southern Holland. Sturgeon similarly threw himself from different heights and positions into and onto multiple sites in the Wittemoor—a literal “getting to know you” phase between artist and bog. In another subtle reference to Beuys, this time reminiscent of the Earth Telephone (1968), Sturgeon, with both feet buried and temples wired to the landscape, seems to exchange messages with the earth in his performance piece Moor Battery.

Acclaimed digital media artist John Sturgeon is perhaps an unlikely protagonist of soil art. Yet his memorable multi-media performance and video works at the “More Moor” International Festival of performance, installation & site specific work provide inspiring new ways of looking at endangered wetland soils. In addition to Falling Moor, and Moor Battery, Sturgeon performed Fishing Moor with German performance artist Insa Winkler. The two artists dressed as anglers and traversed the conservation area with video-camera topped fishing poles. The resulting video portrayed various perspectives of the wetland ecosystem and the interactions of the performers.

The tone of Sturgeon’s work becomes more serious in Narkose. (Fig. 7) This work touches on

14 death as an inevitable aspect of soil. Here, Sturgeon appears buried horizontally “at a geological depth of about 2,000 years.” (Sturgeon 1992). Accompanying the somber performance is a video loop on a monitor near the artist’s head that flashes with images of environmental destruction cut with battle scenes from the Gulf War of 1991. As quickly as human life is obliterated, so are entire ecosystems. The motives may vary, but the irreversible effects carry a similar, unbearable weight. Additionally, an audio track of a text Sturgeon wrote emerges from small speakers in the ground. Dark echoes emanate from the depths of forgotten time and space as poetry to and from the earth. The foreboding content of the images and sounds, and the temporal nature of the digital media that convey them, create a melancholic, even threatening tension in the work. Narkose begs the question in dire metaphors – is this the fate of the earth, or a merely a passing phase of transformation?

15 3.5 Soil and Sculpture – Students Retrace the History of Former Sewage Fields

Located on the northern periphery of Berlin, the Rieselfelder, or former wastewater disposal fields, are the site of acres of anthropogenic soils with a fascinating natural and cultural history. From 1890 to 1985, untreated sewage wastewater was applied to about 1,400 hectares of agricultural land outside the . The disposal of more than 10,000 mm of wastewater in the 1970s rendered agricultural use no longer possible. Upon construction of the purification plant “Schönerlinde,” intensive wastewater application finally came to a close in 1986. In 1987, in honor of the city of Berlin’s 750th anniversary, the GDR attempted to reforest the site as a remediation effort. Unfortunately, this measure had virtually no effect on the site. Most of the trees died, mainly due to seasonal water shortage, nutrient deficiency, and heavy metal contamination. A complete change in soil moisture conditions, from very wet under the constant wastewater infiltration, to relatively dry, with only natural precipitation (ca. 570mm a year), caused the soil to become water repellent (Täumer et al. 2006), and a rapid turnover process of organic matter occurred, which induced increased leaching of heavy metals and nitrates (Hoffmann 2002). To protect the groundwater and reactivate weakened soil functions, a remediation program financed by the European Commission and the city of Berlin was initiated in 1997 under the leadership of the Department of Soil Protection of the Berlin University of Technology (TU-Berlin). For the long- term immobilization of heavy metals and improvement of soil fertility, 30 cm of calcareous lime excavated from a nearby tunnel construction project were applied to the surface and mixed with the contaminated soil up to 90 cm soil depth. As a result, a reforestation program was successfully carried out, and some locations are now used for an artificial groundwater recharge program for pre-purified water of the Schönerlinde facility.

Based on this complex history, TU-Berlin students developed artistic proposals to capture the history of the wastewater disposal fields and make the change of soil properties visible to the public. Inspired by the minimalist forms of the early Earthworks, landscape architecture student, Hardy Buhl, erected a giant soil ”cake” in 2006 (Fig. 8). The 20 m diameter cake was divided by three intersecting mulch pathways, culminating in the center with a granite boulder, left behind by the last ice age, about 10,000 years ago. Several trenches were excavated in the area and the soil profile horizons were horizontally arranged in concentric circles. The uppermost layer of couch grass (Elytrigia repens) sod was placed at the outer perimeter, with deeper, subsoil materials towards the centre. In juxtaposition to the ancient rock at the center, the cake's striped slices revealed the stark anthropogenic signature of the former sewage-dumping site. Every other slice,

16 however, was laid out with lime-enriched soil from remediated areas elsewhere on the site, exposing both the destructive and ameliorative effects of human activity on the soil.

Today, the topography of the site shows little evidence of its former use to the untrained eye. Grassy meadows dotted with willows and poplars border hedge-lined dirt pathways leading up to a little lake on the eastern edge of the site. Managed by the Forestry Department of Berlin-Buch, the 2000-hectare large Rieselfelder are now used as a public park. Installed amidst the site's extensive outdoor sculpture park, the soil cake was both an artistic addition as well as an informative tribute to the Rieselfeld's hidden history. Sensitive to the surrounding ecology of the site, the work was allowed to be reclaimed by vegetation over the course of time and is now no longer visible, except for the top of the granite boulder that peeks out from a sea of couch grass.

17 3.6 Soil and Painting – A Springboard for Other Forms of Soil Art

Since the Upper Paleolithic time, humans have used soil-based pigments to adorn cultural artifacts, dwellings and their own bodies. “Earth paintings” also represent a by-product of the Land Art movement, including some lesser-known works of artists such as Richard Long, Robert Rauschenberg, and Alan Sonfist.

After an introduction to Land and Environmental Art, the TU Department for Soil Protection took the classroom outside. In the heat of the summer months, when the conditions for making lacquer profiles were just right, a series of creative field exercises was carried out in an overgrown urban lot near the TU campus (Fig. 9). Landscape planning- and environmental engineering- students, research fellows, technicians, and visiting scientists were invited to paint their impressions of the site with materials found on or buried in the soil. As participants scurried about collecting samples from different soil profiles, a discussion on urban soils, water and nutrient transport and surface sealing ensued. While waiting for the canvasses to dry, the site itself revealed its complex cultural and natural history. Everyone looked for clues that could be integrated into the artwork. There was an analysis of crumbling remnants of old building materials, the recycling of colorful, weather-beaten trash, the excitement of hitting ground water at the deepest point of the site, and the discovery of hidden fox holes beneath the new shoots of wild locust trees. Though the previous knowledge and experience of making art differed greatly among the participants, everyone was able to piece together their own unique interpretation of the site with paintbrush, stretched canvas, and soil.

18 While the active participation in the experiment was a great success, the lasting effect of such activities remains unclear. Stephen Wilson warns of the specialized blinders often donned by many in scientific fields: “Many scientific and technological researchers define the arts as alien territory… If they are personally interested, they hold stereotypical views of the arts that stops with classical museum and gallery forms such as painting and sculpture” (Wilson 2002a, p. 876). Such a warning is not without reason. Despite the collaborative efforts mentioned earlier, many scientists still view art as something decorative – to be hung on a wall or placed on a pedestal. Two important lessons may be learned, however, from the gritty brushstrokes of our artistic field exercises at the TU-Berlin:

1. Despite their stereotypical identity for the arts, painting and sculpture offer “easy access” to interdisciplinary educational models of combining soil science and art. To mould a figurative form out of a chunk of clay or to sprinkle medium-grained sand onto a canvas represents a creative, even cathartic, hands-on introduction to soil science and soil art. Artistic activities loosen institutional textbook soil science lectures to allow for other forms of knowing and experiencing soil.

2. Painting and sculpture with soil can be a springboard for other forms of artistic experimentation and collaborative research. While they represent an opportunity for combining different fields of interest, the experiment can still be developed further.

3. Interdisciplinary Opportunity and Challenge

In a beautiful a play on words, cultural researcher, Hildegard Kurt (2003, p. 5) compares science, (Wissenschaft), or literally “the making of knowledge” to art as “Wissensform”, literally “the form of knowledge”. Both are equal and necessary counterparts that, when used together, contribute to a holistic experience of understanding and appreciation. In a similar sense, Stephen Wilson (2002b) asserts that both art and science are carried out as cultural acts. Wilson (2002b, p. 18) compares the parallel roles of contemporary artistic and scientific practice:

“Both value the careful observation of their environments to gather information through the senses. Both value creativity. Both propose to introduce change, innovation, or improvement over what exists. Both use abstract models to understand the world. Both aspire to create works that have universal relevance.”

In an age of growing common interests and a collective sense of environmental responsibility, practitioners from both fields have become increasingly curious about the methods and research areas of the other. In addition to learning about various artistic activities with and about soils, we

19 were also curious to find out how soil scientists felt about the field of soil art. At the German Soil Science Society’s annual conference in 2007, we distributed a survey on soil science, aesthetics and art at a session on soil science, society and education. We asked members to share their opinions about the importance of this unusual aspect of soil science, and about their potential willingness to get involved. While 64% regarded the interdisciplinary direction of “soil art” as important, 85% answered that they would be personally interested in cooperating with an artist. These results suggest good potential for future soil science and art collaborations. But how?

Stephen Wilson’s book, Information Arts: Intersections of Art, Science, and Technology, provides hundreds of examples of how artists have used and developed scientific research in their works, from fields such as atomic physics, robotics, microbiology and genetics. Conversely, we should ask how artists might be integrated into research projects – and more specifically, soil science research projects - not only with the goal of generating greater public understanding or promoting cultural values, but also by contributing their own creativity to finding solutions to problems such as e.g. soil erosion, contamination, or degradation. How can the field of soil science more openly incorporate aesthetic and artistic values that resonate with art audiences or a wider public? How can artists be paired with scientists in productive research partnerships? How can such pooling of creativity be further fostered in academic settings to influence conservation strategies?

To address these questions, it is worth mentioning a few organizations that document and support “best practice” examples of interdisciplinary projects. The following groups could inspire future collaboration between scientists and artists specializing in soils: the Leonardo and International Society for the Arts, Sciences and Technology (ISAST), greenmuseum.org online network for environmental arts, the Art and Science Collaborations Inc. (ASCI), the RSA Arts and Ecology Program, the Carnegie Mellon University Studio for Creative Inquiry, and the MIT Center for Advanced Visual Studies (CAVS). The following museums may also offer exciting new opportunities for soil science and art collaborations: the Underworld Exhibition in Osnabrück, Germany (Unterwelten Ausstellung des Natur und Umweltmuseums am Schölerberg), the ISRIC World Soil Museum in Wageningen, NL, the Underground Adventure at the Field Museum of Chicago, the Dig It! The Secrets of the Soil exhibition at the Smithsonian National Museum of Natural History in Washington D.C., and the Dokuchaev Central Soil Museum in St. Petersburg, Russia.

Interdisciplinary projects, such as some of those mentioned in this paper, and promoted by the organizations above, are unique in that they are either initiated by or include artists in solving local 20 and regional environmental problems. The artistic element of involvement need not always result in an object or exhibition, but can rather be seen as a creative phase of guidance in restoration and conservation efforts. Verging on an “Is it Art?” aesthetic, the trend towards creative collaboration promises some interesting solutions to difficult environmental dilemmas, but also calls for a progressive cultural context that can support the new environmental avant-garde. Wilson (2002c, p. 131) warns of the inevitable challenges of interdisciplinary environmental and ecological art:

Some analysts object that it is difficult to distinguish ecological art projects from political or scientific interventions. As art moves increasingly into actions in real-life settings with multiple non-art actors, the differentiation becomes difficult. How are these projects any different than if they were initiated by a political or scientific group? Other analysts suggest that definitions are changing and that new kinds of public art are emerging that do not resemble old forms. An even more radical suggestion is that the distinction between art and non-art is no longer visible.

In a Neo-Renaissance reconciliation of art and science, we must constantly examine what distinctions and parallels can be made between an ever converging critical art-world and a culturally literate scientific community. This is necessary for any attempt to combine soil science and art. Both fields must inform themselves of the other’s developments if they are to take part in a constructive dialogue. Both must guide each other in achieving common goals of environmental change. Conscious cross-referencing and frequent communication is needed. This is not a theoretical observation, but a call for action. Professional artists should be invited more often to conferences, into laboratories, and to participate in engineering and agricultural experiments, while scientists might offer their expertise at environmental art symposiums, exhibitions and seminars. Creativity goes both ways. It must only be recognized and cultivated in settings that are home to both the arts and the sciences.
