Revision Update on Nutrient Management Standards: Progress and Future Actions

The revisions for the Nutrient Management (590 Standard) have made significant progress, including the completion of Draft 590 and specifications for Nutrient Management (S-590). Internal reviews have been conducted, and necessary edits to the draft are being finalized. Recent discussions at the NRCS Four-State Meeting, involving Iowa, Missouri, Kansas, and Nebraska, highlighted state-specific updates and the Phosphorus Index (PI). Current tools are effective, and emphasis is being placed on evaluating PI changes and exploring guidelines, such as daily application maps for better nutrient management.
