WitrynaSoil organic matter (SOM) has many functions, the relative importance of which differ with soil type, climate, and land use. Commonly the most importantfunction of OM in soil is as a reserve of the nitrogen and other nutrients required by plants, and ultimately by the human population. Other important functions include: the formation of stable ... WitrynaMicrobial Soil Orga nic Matter Decomposition. Organic matter decomposition serves two functions for the microorganisms, providing energy for growth and suppling carbon for the formation of new cells. Soil organic matter (SOM) is composed of the "living" (microorganisms), the "dead" (fresh residues), and the "very dead" (humus) fractions.

Witryna27 lis 2024 · The sequestration of carbon in soil organic matter is one of the main cost-effective climate mitigation strategies for removing global-warming carbon dioxide (CO 2) from the atmosphere. Soil carbon sequestration is a process whereby CO 2 is removed from the atmosphere by vegetation, and stored in the soil’s pool of organic carbon.
WitrynaOrganic matter influences the physical conditions of a soil in several ways. Plant residues that cover the soil surface protect the soil from sealing and crusting by raindrop impact, thereby enhancing rainwater infiltration and reducing runoff.
