Quick Facts...
Nitrogen in the air is the ultimate source of all soil nitrogen.
Nitrogen may enter the soil through rainfall, plant residues, nitrogen fixation by soil organisms, animal manures and commercial fertilizers.
There is no difference between the nitrogen that enters the plant from commercial fertilizers and that from organic products.
Nitrogen may be lost from the soil by plant removal, volatilization, leaching or erosion.
Leaching of nitrate is a pollution hazard; control nitrogen losses with proper management practices.
To get the maximum benefit from nitrogen fertilization with a minimum pollution hazard you must understand nitrogen properties and transformations.
