The absorption of solar radiant energy by the earth's surface and its release as heat into the atmosphere; longer infrared heat waves are absorbed by the air, principally by carbon dioxide and water vapor, thus, the atmosphere traps heat much as does the glass in a greenhouse.
Industry:Earth science
That part of the phosphorus in a fertilizer that is soluble in water as determined by prescribed chemical tests.
Industry:Earth science
The process whereby nitrate is reduced by plants and microorganisms to ammonium for cell synthesis (nitrate assimilation, assimilatory nitrate reduction) or to nitrite by bacteria using nitrate as the terminal electron acceptor in anaerobic respiration (respiratory nitrate reduction, dissimilatory nitrate reduction). Sometimes used synonymously with "denitrication".
Industry:Earth science
The ability of a nodule symbiont or pathogenic microorganism to establish itself and live in soil as a saprophyte.
Industry:Earth science
The breakdown of rocks and minerals due to the presence of water and other components in the soil solution or changes in redox potential.
Industry:Earth science
The well decomposed, more or less stable part of the organic matter in mineral soils. Humas is an organic soil material which is also one of the USDA textures of muck (sapric soil material), mucky peat (hemic soil material), or peat (fibric soil material. ) Most likely it is muck.
Industry:Earth science
The fractions of the various soil separates in a soil sample, often expressed as mass percentages.
Industry:Earth science
The flux (or rate) of water infiltration into soil when water at atmospheric pressure is maintained on the atmosphere-soil boundary, with the flow direction being one-dimensionally downward.
Industry:Earth science
The branch of soil science concerned with soil-inhabiting microorganisms, their functions, and activities.
