Document Summary
Atmospheric n2 fixation: lighting energy and heat converts n2 to no2. Nitrification: mineralization: organic n nh4, n immobilization is the opposite, nh4. Denitrification: leave the ecosystem and enters the atmosphere. No2: anaerobic, high in environments with low o2 and plenty of. No3: ex. deep ocean, pantanal wetland, wet soils with high no3, enhanced denitrification by wetting and drying. Levels (alternating nitrification and denitrification: effects, helps to alleviate n pollution in aquatic and terrestrial ecosystems, no3. : harmful in drinking water and causes algal blooms: no: precursor to ozone formation in troposphere (where we are, n2o: potent greenhouse gas that destroys ozone in stratosphere. 3-) form: mineralization: fungi and bacteria break down detritus, release po4. Particular p: p captured on filter, including organic and inorganic. Soluble reactive p (srp): dissolved p passing through 0. 45 um membrane (primarily inorganic po4. Important source of p to offshore ocean atmospheric dust: african dust may fertilize amazon rainforest with p, p crucial fertilizer, po4.
