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. 2013 KY NRCS (590) Nutrient Management Standard Highlights: • 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.
