NRCS has been working with owners of animal feeding operations to manage manure and animal mortality since the passing of the Clean Water Act of 1972.  The NRCS strategy to prevent degradation of the nation’s water resources from confined animal feeding operations has been to work with private landowners on a voluntary basis to prevent the discharge of contaminated runoff from animal production areas and apply manure to agricultural land in a way to benefit from its nutrient and soil building characteristics.  Landowners may also work with NRCS conservation planners to address air resource concerns and take advantage of potential energy value in the manure.  The planning and technical assistance provided by NRCS results in Comprehensive Nutrient Management Plans that include manure management and conservation practices that can be often be implemented with financial assistance.
