What agricultural practices can help control nutrient loading rates to the surface waters?

0

Environmental Protection Agency has described eight ways in its Agricultural Management Practices for Water Quality Protection, module that can help control nutrient transport to surface and ground waters. • Conservation Tillage- it involves leaving 30% crop residues on the soil surface after tillage. This practice can reduce soil-erosion, runoff, preserve soil moisture, hold nutrients on the applied area and improve soil structure, air and water quality. • Crop Nutrient Management- this practice requires accounting and inputting nutrients in quantities that may optimize crop-growth while reducing their movements off the field where they are applied to. This practice effectively controls the nutrient build-up in soils. • Pest Management- varied methods for keeping insects, weeds, disease, and other pests below economically harmful levels while protecting soil, water, and air quality.
