This soil has formed from B Horizon - Subsoil long term weathering of granite into soil like materials. C Horizon (deeper) Native Forest Soil Leaf litter and roots (> 5 T/Ac/year are “bio- processed” to form humus, which is the dark black material seen in this topsoil layer. In the process, nutrients and energy are released to plant uptake and the higher food chain. These are the “natural soil cycles” that we attempt to manage today. Soil Profiles Soil profiles are two-dimensional slices or exposures of soils like we can view from a road cut or a soil pit. Soil profiles reveal soil horizons, which are fundamental genetic layers, weathered into underlying parent materials, in response to leaching and organic matter decomposition. Fig. 1.12 -- Soils develop horizons due to the combined process of (1) organic matter deposition and decomposition and (2) illuviation of clays, oxides and other mobile compounds downward with the wetting front. In moist environments (e.g. Virginia) free salts (Cl and SO4 ) are leached completely out of the profile, but they accumulate in desert soils.

To achieve this purpose, three different wheel traffic applications (no traffic, one pass, and two passes) were used. In the experiments, two different methods of manure applications (surface and subsurface) and three different farmyard manure amounts were used with a control plot (N0), 40 Mg ha–1 (N40), and 80 Mg ha–1 (N80). Manure was applied in both years of the experiment in the first week of April. For the subsurface application, the manure was mixed in at approximately 10 cm of soil depth with a rotary tiller. According to the results, soil temperature, soil moisture, penetration resistance, and bulk density increased with increasing wheel traffic except 2CO emission for 2014 and 2015. CO2 emission values decreased with traffic. Subsurface manure application caused more 2CO emission compared to surface application. The increase in manure amounts led to an increase in CO2 emission and soil moisture content. -
Soil Ecology
LSC 322 Laboratory 10 LAB #10: SOIL ECOLOGY Soil is one of the earth’s most important resources. For a community of plants and animals to become established on land, soil must first be present. Further, soil quality is often a limiting factor for growth many systems. Soil is a complex mixture of inorganic and organic materials, microorganisms, water and air. The weathering of bedrock produces small grains of rock that accumulate as a layer on the surface of the earth. There they are altered by biology, becoming mixed with organic matter, which results from the decomposition of the waste products and dead tissue of living organisms to form humus. The soil formation process is very slow (hundreds to thousands of years), so it can be very detrimental to a community if the soil is lost through erosion or its quality degraded by pollution or misuse. Soil Sampling As a class, we will identify interesting soil ecosystems on campus that we would like to examine further. Your small group will be assigned to collect one of those samples. Using a trowel, you will scoop the top 5 cm (this is where most of the biological “action” happens) into a ziplock bag. Also, take notes to record the environmental surroundings. What is the land usage? What plants are growing here? What is the soil moisture? These environmental characteristics will influence many aspects of the soil. Questions - Describe the environment from which you took your soil sample. Include all of the information from your notes. - How do these conditions relate to the soil characteristics measured during the lab exercise (texture, nutrients, pH, and biota)? After samples are collected, we will return to the lab and measure the following characteristics: Soil Texture Soil texture refers to the proportion of sand, silt, and clay present in a soil, which differ in their particle size. -

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. -
Soil Quality: Why and How?
Geoderma 114 (2003) 145–156 www.elsevier.com/locate/geoderma Soil quality: why and how? Douglas L. Karlena,*, Craig A. Ditzlerb, Susan S. Andrewsa a USDA-ARS National Soil Tilth Laboratory, 2150 Pammel Drive, Ames, IA 50011-4420, USA b National Soil Survey Center, 100 Centennial Mall North, Lincoln, NE 68508-3866, USA Abstract The soil quality concept evolved throughout the 1990s in response to increased global emphasis on sustainable land use and with a holistic focus emphasizing that sustainable soil management requires more than soil erosion control. The concept includes two areas of emphasis—education and assessment—both based soundly on principles of soil science. Soil quality test kits, farmer-based scorecards, visual assessment procedures, fact sheets, and video presentations were developed as educational materials because many people have no basis to recognize, understand or appreciate the complexity of soil resources. Assessment tools for indexing soil quality at various scales were pursued to show the multiple functions (e.g. nutrient and water cycling, filtering and buffering of contaminants, decomposition of crop residues and other organic matter sources, and recycling of essential plant nutrients) that soils provide as the foundation for sustainable land management. Worldwide research and technology transfer efforts have increased awareness that soil resources have both inherent characteristics determined by their basic soil formation factors and dynamic characteristics influenced by human decisions and management practices. Soil quality assessment and education are intended to provide a better understanding and awareness that soil resources are truly living bodies with biological, chemical, and physical properties and processes performing essential ecosystem services. -

Dynamics of Carbon 14 in Soils: a Review C
Radioprotection, Suppl. 1, vol. 40 (2005) S465-S470 © EDP Sciences, 2005 DOI: 10.1051/radiopro:2005s1-068 Dynamics of Carbon 14 in soils: A review C. Tamponnet Institute of Radioprotection and Nuclear Safety, DEI/SECRE, CADARACHE, BP. 1, 13108 Saint-Paul-lez-Durance Cedex, France, e-mail: [email protected] Abstract. In terrestrial ecosystems, soil is the main interface between atmosphere, hydrosphere, lithosphere and biosphere. Its interactions with carbon cycle are primordial. Information about carbon 14 dynamics in soils is quite dispersed and an up-to-date status is therefore presented in this paper. Carbon 14 dynamics in soils are governed by physical processes (soil structure, soil aggregation, soil erosion) chemical processes (sequestration by soil components either mineral or organic), and soil biological processes (soil microbes, soil fauna, soil biochemistry). The relative importance of such processes varied remarkably among the various biomes (tropical forest, temperate forest, boreal forest, tropical savannah, temperate pastures, deserts, tundra, marshlands, agro ecosystems) encountered in the terrestrial ecosphere. Moreover, application for a simplified modelling of carbon 14 dynamics in soils is proposed. 1. INTRODUCTION The importance of carbon 14 of anthropic origin in the environment has been quite early a matter of concern for the authorities [1]. When the behaviour of carbon 14 in the environment is to be modelled, it is an absolute necessity to understand the biogeochemical cycles of carbon. One can distinguish indeed, a global cycle of carbon from different local cycles. As far as the biosphere is concerned, pedosphere is considered as a primordial exchange zone. Pedosphere, which will be named from now on as soils, is mainly located at the interface between atmosphere and lithosphere.
