1 2013 KY NRCS (590) Nutrient Management Standard Highlights: NRCS 590 is now only required for producers applying to receive NRCS financial or technical assistance with a Nutrient Management resource concerns. NRCS Air Quality is addressed in the standard for the first time. NRCS personnel and TSP’s must be certified to write nutrient management plans (CNMP’s and NMP’s.) The certification process is complicated and takes a while. Nitrogen and Phosphorus Risk Assessments must be used on every field. (A New N&P index has been developed.) Producers no longer have the choice to choose a threshold approach vs. a risk assessment approach for planning nutrient application. Every application field must have a RUSLE2 soil loss assessment ran to determine soil loss. NRCS planning criteria must be met for any fields receiving nutrients (Soil loss tolerance levels must not be exceeded.) Considerations must be made when planning nutrient applications to tile fields for the first time. (Closing tile outlet in the winter, changing application timing, reducing application rates, etc.) The thresholds apply only to manure applications. It is assumed that AGR-1 is being followed for those fields receiving commercial fertilizer, with a documented agronomic need.

2 Setbacks will follow KY Ag Water Quality Authority setbacks. NRCS Nutrient Management Plan’s are for land application of nutrients only. NRCS CNMP’s are for those AFO/CAFO operations that produce animal waste. They do not necessarily have to land apply it. (Example: some poultry operations produce and export all the litter.) *Remember when reading a NRCS Practice Standard; each Criteria that applies has to be met, and Considerations are things that should be considered when planning KY NRCS (590) Nutrient Management Standard Highlights:
