Protection Activity: Best Management Practices

Nutrient management includes managing the amount, source, placement, form, and timing of nutrient and soil amendment applications. Nutrient management practices can minimize the potential for environmental damage including agricultural nonpoint source pollution of surface and ground water sources; maintain or improve the physical, chemical, or biological condition of soil; prevent or reduce excess nutrient concentrations in the soil; properly use all sources of organic material, including animal waste, as a plant nutrient source; and save money.

Proper fertilizer application rates limit fertilizer to an amount necessary to achieve realistic crop yield goals. Yearly soil sampling will help to determine plant nutrient needs and to make accurate fertilizer recommendations. Optimal application rate calculation includes crediting other sources that contribute nitrogen and phosphorous to the soil.
