N transformations

For 330 Nitrogen transformations vocab, many from Chapin et al 2011

Ammonification Conversion of dissolved organic nitrogen to ammonium; synonymous with N mineralization.
Chitin Complex polymer containing N derived from fungal cell walls and insect exoskeletons.
Denitrification Conversion of nitrate to gaseous forms (N2, NO, and N2O).
Deposition Atmospheric input of materials to an ecosystem.
Dissolved organic nitrogen (DON) Water-soluble organic nitrogen compounds.
Exoenzymes Enzyme that is secreted by an organism into the environment.
Immobilization Removal of inorganic nutrients from the available pool by microbial uptake and chemical fixation.
Leaching Downward movement of materials in solution. This can occur from the canopy to the soil, from soil organic matter to the soil solution, from one soil horizon to another, or from the ecosystem to ground water or aquatic ecosystems.
Mineralization Conversion of carbon and nutrients from organic to inorganic forms due to the breakdown of litter and soil organic matter.
Nitrification Conversion of ammonium to nitrate in the soil.
Uptake Absorption of water or mineral by an organism or tissue.
