Soil organic matter (SOM) is the organic matter content of soil, consisting of plant and animal detritus at various stages of decomposition, cells and tissues of soil microbes, and substances that soil microbes synthesize (Brady & Weil, 2008).
Soil organic matter (SOM) is the organic matter component of soil, consisting of plant and animal detritus at various stages of decomposition, cells and tissues of soil microbes, and substances that soil microbes synthesize.
Nov 25, 2021 · Define soil organic matter and list its main components. Evaluate the importance of organic matter on soil physical, chemical and biological properties and processes. Explain the sources and turnover processes of soil organic matter. Discuss the spatial distribution and land management of soil organic matter.
Soil organic matter is the key to building and maintaining healthy soils because it has such great positive influences on essentially all soil properties—aggregation, nutrient availability, soil tilth and water availability, biological diversity and so on— helping to grow healthier plants.
Nov 18, 2023 · Organic matter improves soil structure, which results in increased water infiltration following rains and increased water-holding capacity of the soil; it also enhances root growth into more permeable soil.
Soil organic matter holds 10 to 1,000 times more water and nutrients than the same amount of soil minerals. Beneficial soil organisms become more numerous and active with diverse crop rotations and higher organic matter levels.
