Title
Nitrogen in Mississippi Soils
Abstract
Field crops typically require more nitrogen (N) than Mississippi soils provide in a growing season. Fertilizer or manure sources of N must be added for economical crop production. However, too much available N may lower yields and lessen crop quality. If soil N as nitrate (NO3 - ) supply is greater than crop demand, the excess NO3 - may enter ground or surface water.
Nitrogen behavior is complex, but farmers must understand it so they can manage it for greatest profit and least environmental impact.
