Nitrogen

Nitrogen is an essential nutrient for crop growth and production. However, unneeded application or poor efficiency results in increased production cost and lost economic return. In addition, nitrogen management has environmental importance since losses from agricultural systems have been identified as likely contributors to elevated surface or groundwater nitrate concentrations, impairment of freshwater bodies, and hypoxia of coastal waters. This module will cover important concepts of nitrogen management in agronomic systems for profitable and environmentally safe crop production.
