Usually soil volumetric water content is used. Usually determined based on empirical data. Skye Wills. NCSS, 2011. Soil and Ecosystem Change. Soil Change Guide. Document change in soil function applicable over the entire extent of a soil series or component phase. When possible, Ecological Sites and associated State and Transition Models inform study design and interpretation. THK JAIN COLLEGE. WHAT IS SOIL EROSION. . Soil erosion is a type of soil degradation in which there is wearing away or displacement of the upper layer of soil (topsoil).. Soil erosion is a global threat in the current world scenario.. Objectives. Define: soil respiration and soil microbes. Explain the role of soil respiration in determining soil health. Diagram the role of soil respiration in the cycle of life on earth. List and explain inherent factors that affect soil respiration. Objectives. Define: immobilization, mineralization, phosphorus cycle, phosphorus fixation, soil phosphate. Diagram the relationship of phosphorus inputs and soil processes. List and describe inherent factors that affect soil phosphorus. Figure 3-24. Fig. 3-24a, p. 69. Mosaic of closely packed pebbles, boulders. Weak humus-mineral mixture. Dry, brown to reddish-brown with variable accumulations of clay, calcium and carbonate, and soluble salts. Objectives. Define: soil organic matter. Explain the role of inherent factors affecting soil organic matter. Explain the five soil organic matter management practices. Explain how soil organic matter relates to soil function.
