- Company Profile:
A USDA agency responsible for developing and carrying out national soil and water programs in cooperation with landowners, operators, and others. It was created in 1994 reorganization legislation by merging the Soil Conservation Service and many of the conservation cost-sharing programs of the Agricultural Stabilization and Conservation Service. The NRCS is responsible for developing and carrying out national soil and water conservation programs in cooperation with landowners, farm operators, and others. More than 70% of the approximately 12,000 employees work at the field level.

The nitrogen ion, NO3-, is derived from nitric acid and is an important source of nitrogen in fertilizers. Nitrate pollution of drinking water, shallow wells being particularly vulnerable, is of concern because infants are especially sensitive. A nitrate drinking water standard has been set under the Safe Drinking Water Act. An Environmental Protection Agency national survey of drinking water wells conducted from 1988 to 1990 indicated that 2.4% of rural domestic wells contained nitrate at or above the 10 mg/L standard. Higher rates of contamination have been found in areas of high vulnerability; for example, surveys along the upper Des Moines river indicate that 20 to 30% of wells exceed the standard.
Industry:Agriculture
An element found in the air and in all plant and animal tissues. For many crops, nitrogen fertilizer is essential for economic yields. However, nitrogen can also be a pollutant when nitrogen compounds are mobilized in the environment (e.g., leach from fertilized or manured fields), are discharged from septic tanks or feedlots, volatilize to the air, or are emitted from combustion engines. As pollutants, nitrogen compounds can have adverse health effects (see nitrate and air pollution) and contribute to degradation of waters (see eutrophication).
Industry:Agriculture
From long-term toxicological studies of agricultural chemical active ingredients, levels which indicate a safe, lifetime exposure level. Used in setting pesticide residue tolerances.

A method of planting crops that involves no seed bed preparation other than opening the soil to place individual seeds in holes or small slits; usually no cultivation during crop production; chemical weed control is normally used. May also be referred to as slot tillage or zero cultivation. See, for comparison, conservation tillage and minimum tillage.
