The effort includes understanding the functions of soil microbiotic crusts and exploring the potential to sequester atmospheric carbon in soil organic matter.
22.
Tilling results in soil organic matter being broken down much more rapidly, and carbon is lost from the soil into the atmosphere.
23.
Petroleum hydrocarbons, less chlorinated solvents like vinyl chloride, soil organic matter, and reduced inorganic compounds are all compounds that can act as electron donors.
24.
The products from the living organisms metabolism are the secondary sources of soil organic matter that also includes the dead corpses of these organisms.
25.
Liming acidic soils can increase potassium retention in some soils by reducing leaching; practices that increase soil organic matter can also increase potassium retention.
26.
Although magnesium and manganese are produced by weathering, exchanges between soil organic matter and living cells account for a significant portion of ecosystem fluxes.
27.
The problem is that release of nitrogen from soil organic matter can make up any shortfall of nitrogen from legumes for a decade or more.
28.
Storage is in the form of non-labile soil organic carbon ( SOC ), which is part of the soil organic matter ( SOM ) pools.
29.
Because soil organic matter accumulates in the upper layer, most gelisols are black or dark brown in soil color, followed by a shallow mineral layer.
30.
The nutrients adsorbed onto the surfaces of clay colloids and soil organic matter provide a more accessible reservoir of many plant nutrients ( e . g.
