42 Nitrogen Risk Assessment section Add to end of 3rd paragraph: "Manure applications in late summer or early fall on AA, A or B Hydrologic Soil Groups require a cover crop to be established, or the N index completed. Fall application rates cannot exceed what would be applied in the spring unless an N index calculation is completed."
43 Phosphorus Risk Assessment section Add to beginning of last paragraph: "Manure applied to soils with soil test values in excess of 30 mg/L phosphorus must complete a phosphorus index to determine separation distance from surface water. Refer to NMAN software or Nutrient Management Workbook."
