IMPORTANT TERMINOLOGIES
N MINERALIZATION RATE: The rate at which organic nitrogen is converted to ammonium and nitrate is termed as N mineralization rate.
AMMONIFICATION: The production of ammonia from organic nitrogenous materials of the soils. (Formation of ammonium from organic compounds)
AMINIZATION: The breakdown of organic matter by certain heterotrophic bacteria and fungi, resulting in the release of amines, amino acids and urea.
NITRIFICATION: The conversion of ammonia nitrogen to nitrate nitrogen. (Oxidation of ammonium to nitrate)
DENITRIFICATION: The conversion of nitrate and nitrite into molecular nitrogen or nitrous oxide through microbial processes.
IMMOBILIZATION: The conversion of inorganic nitrogen ions (NH4+ NO3) into organic forms
VOLATILIZATION: Gaseous ammonia loss to the atmosphere from nitrogen fertilizers.
LEACHING: The loss of nitrate ions into water bodies, rivers and lakes.
