Nutrient losses
For 330 nutrient losses vocab, many from Chapin et al 2011
Term | Definition |
---|---|
Ammonia volatilization | Gaseous loss of of ammonia resulting from enzymatic breakdown of urea orignating from animal urine or fertilizer; CO2 is also released. |
Catchment | A river or stream and all the terrestrial surfaces that drain into it; synonymous with drainage basin or watershed. |
Denitrification | Conversion of nitrate to gaseous forms (N2, NO, and N2O). |
Hillslope processes | Processes by which water, dissolved solids, sediments, and rocks move down slope. |
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. |
Suction lysimeter | Porous ceramic cup sampling device used to extract pore-water solution from unsaturated soil. |
Nitrogen saturation | Ecosystem conditionin which nitrogen inputs exceed plant and microbial nitrogen requirements so that the system loses nitrogen to the atmosphere and to groundwater and streams. |
Urease | An exoenzyme that breaks down urea from animal urine or fertilizer into carbon dioxide and ammonia. |
