Paleosols are now well known reservoirs of paleoclimate information. Two the greatest difficulties impeding the extraction of more quantitative environmental information from these soils are (1) difficulties in developing precise chronological age constraints and (2) extracting non-integrated climatic signals from the soil’s chemistry. On-going advances in laboratory instruments and the development of new techniques have opened emerging avenues for paleosol dating and paleoclimate research. Cosmogenic surface exposure dating is becoming a mature field. However, more recently, the use of cosmogenic nuclides to estimate burial ages has been conducted, with the recent combined use of 26Al, 10Be, and 21Ne pushing the window of application further back in time: well into the Miocene (Balco and Shuster, 2009). This application has been further enhanced by much more rapid methods of 21Ne measurements by some laboratories. Soil carbonate laminations on gravels have been recognized to retain potentially 105 y records of stable C and O isotopes.

Soil profiles reveal soil horizons, which are fundamental genetic layers, weathered into underlying parent materials, in response to leaching and organic matter decomposition.

  • Paleoenvironmental Constraints from Paleosol-Loess Sequences: Evaluating Clumped (∆47) Isotopic Records in Biogenic and Pedogenic Carbonate
    Paleoenvironmental constraints from paleosol-loess sequences: evaluating clumped (∆47) isotopic records in biogenic and pedogenic carbonate Katharine Huntington, Department of Earth and Space Sciences The project goal was to advance understanding of how the geochemistry of biogenic and pedogenic (formed in soil) carbonates record surface environmental temperatures and soil water compositions relevant to the interpretation of proxy records in Quaternary loess-paleosol sequences and cultural layers. Reconstructing Quaternary paleoenvironments is important for a broad range of paleoclimate, geology, biology, anthropology and archaeology studies. The geochemistry of carbonate minerals formed at and near the Earth surface can provide quantitative environmental constraints including the δ18O values of water, δ13C-based information about vegetation, and most recently, estimates of Earth-surface temperatures from clumped isotope (∆47) thermometry. Early efforts to develop clumped isotope thermometry in modern-Holocene soils raise many 18 questions about how to interpret not only ∆47 temperatures but also conventional δ O and δ13C values in soil and loess carbonates. We conducted a study of biogenic, pedogenic, and geogenic carbonates of different types from two Quaternary paleosol-loess deposits, the Nussloch (Rhine Valley, SW Germany) and Palouse (eastern Washington state) loess-paleosol sequences. Carbonate δ18O, δ13C 14 and ∆47 analyses were conducted in the University of Washington IsoLab as well as C dating of carbonates to determine their age and pedogenic vs. geogenic nature. In the 18 13 Nussloch, the δ O, δ C and Δ47 data for multiple carbonate types revealed the effects of geogenic carbonate input, pedogenesis and environmental factors on the isotopic variations, and showed that geogenic “bulk loess” carbonates that are poor environmental proxies can still provide important context for interpreting the isotopic signature of pedogenic and biogenic carbonates (Zamanian et al., in revision).

Soil organisms are important elements for preserved ecosystem biodiversity and services thus assess functional and structural biodiversity in arable soils is interest. One of the main threats to soil biodiversity occurred by soil environmental impacts and agricultural management. This review focuses on interactions relating how soil ecology (soil physical, chemical and biological properties) and soil management regime affect the microbial diversity in soil. We propose that the fact that in some situations the soil is the key factor determining soil microbial diversity is related to the complexity of the microbial interactions in soil, including interactions between microorganisms (MOs) and soil. A conceptual framework, based on the relative strengths of the shaping forces exerted by soil versus the ecological behavior of MOs, is proposed. Plant-bacterial interactions in the rhizosphere are the determinants of plant health and soil fertility. Symbiotic nitrogen (N2)-fixing bacteria include the cyanobacteria of the genera Rhizobium, Free-livingBradyrhizobium, soil bacteria Azorhizobium, play a vital Allorhizobium, role in plant Sinorhizobium growth, usually and referred Mesorhizobium.

To contribute towards an improvement of actual estimates, soil CO2,CH4, and N2O fluxes were measured in two different land-use types in a hilly area of South China. This study showed 2 years continuous measurements (twice a week) of GHG fluxes from soils of a pine plantation and a longan orchard system. Impacts of environmental drivers (soil temperature and soil moisture), litter exclusion and land-use (vegetation versus orchard) were presented. Our results suggested that the plantation and orchard soils were weak sinks of atmospheric CH4 and significant sources of atmospheric CO2 and N2O. Annual mean GHG fluxes from soils of plantation À1 À1 À1 À1 and orchard were: CO2 fluxes of 4.70 and 14.72 Mg CO2–C ha year ,CH4 fluxes of À2.57 and À2.61 kg CH4–C ha year ,N2O fluxes À1 À1 of 3.03 and 8.64 kg N2O–N ha year , respectively.

Wisconsin Geological and Natural History Survey, Madison, Wisconsin 53705, USA ABSTRACT A paleosol beneath the Upper Cambrian Mount Simon Sandstone in Wisconsin provides an opportunity to evaluate the characteristics of Cambrian weathering in a subtropical climate, having been located at 207S paleolatitude 500 My ago. The 285-cm-thick paleosol resulted from advanced chemical weathering of a gabbroic protolith, recording a total mass loss of 50%. Weathering of hornblende and plagioclase produced a pedogenic assemblage of quartz, chlorite, kaolinite, goethite, and, in the lowest part of the profile, siderite. Despite the paucity of quartz in the protolith and 40% removal of SiO2 from the profile, quartz constitutes 11%–23% of the pedogenic mineral assemblage. Like many other Precambrian and Cambrian paleosols in the Lake Superior region, the paleosol experienced potassium metasomatism, now con- taining 10%–25% mixed-layer illite-vermiculite and 5%–44% potassium feldspar.

    Sustaining the Pedosphere: Establishing A Framework for Management, Utilzation and Restoration of Soils in Cultured Systems Eugene F. Kelly Colorado State University Outline •Introduction - Its our Problems – Life in the Fastlane - Ecological Nexus of Food-Water-Energy - Defining the Pedosphere •Framework for Management, Utilization & Restoration - Pedology and Critical Zone Science - Pedology Research Establishing the Range & Variability in Soils - Models for assessing human dimensions in ecosystems •Studies of Regional Importance Systems Approach - System Models for Agricultural Research - Soil Water - The Master Variable - Water Quality, Soil Management and Conservation Strategies •Concluding Remarks and Questions Living in a Sustainable Age or Life in the Fast Lane What do we know ? • There are key drivers across the planet that are forcing us to think and live differently. • The drivers are influencing our supplies of food, energy and water. • Science has helped us identify these drivers and our challenge is to come up with solutions Change has been most rapid over the last 50 years ! • In last 50 years we doubled population • World economy saw 7x increase • Food consumption increased 3x • Water consumption increased 3x • Fuel utilization increased 4x • More change over this period then all human history combined – we are at the inflection point in human history. • Planetary scale resources going away What are the major changes that we might be able to adjust ? • Land Use Change - the world is smaller • Food footprint is larger (40% of land used for Agriculture) • Water Use – 70% for food • Running out of atmosphere – used as as disposal for fossil fuels and other contaminants The Perfect Storm Increased Demand 50% by 2030 Energy Climate Change Demand up Demand up 50% by 2030 30% by 2030 Food Water 2D View of Pedosphere Hierarchal scales involving soil solid-phase components that combine to form horizons, profiles, local and regional landscapes, and the global pedosphere.
