Nitrogen is required by the plant in greater quantities than any other element except carbon, hydrogen, and oxygen. Nitrogen plays a role in numerous plant functions and is an essential component of amino acids, proteins, and nucleic acids. The goal of all applied nutrients is to maximize plant uptake while minimizing nutrient losses. Mycorrhizae: Impacts on Production January - January Quick Bibliography Series no.

Sixty percent agricultural use is correlated with medium high and medium nitrogen concentrations in the Southeast. A high percentage of forest and low or medium low nitrogen concentrations are found in the Great Lakes/Northeast region and the Pacific Northwest.

Connecticut Department of Environmental Protection, DEP Bulletin 28 Hartford, Connecticut Maczka, C., S. Pang, D. Policansky and R. Wedge. Nitrous oxide (N 2 O) is a potent greenhouse gas that can result in nitrogen loss from the soil.
The scientific literature is deficient in studies that measure N 2 O emissions, NO 3 leaching, and crop performance across multiple sources of nitrogen fertilizer and changes in field practices.
However, there are tools and strategies available to consultants and producers to improve nitrogen use. Agriculture accounts for 70%–80% of total pesticide use, and 60% of agricultural use is herbicides (Nowell et al., ).
Environmental concerns led to reductions in the use of persistent pesticides such as DDT, which was banned inbut little is known of the breakdown process or persistence of contemporary pesticides.
The Mississippi River is, in many ways, the nation's best known and most important river system. Mississippi River water quality is of paramount importance for sustaining the many uses of the river including drinking water, recreational and commercial activities, and support for the river's ecosystems and the environmental goods and services they provide.
