Phosphorus management is an important aspect of the USDA-NCRS nutrient management standard. Anyone applying animal waste or fertilizer in a nutrient-impaired subwatershed must determine potential phosphorus loss from each field. This publication describes in great detail the P-Index or Phosphorus Loss Assessment Tool that is used in North Carolina for this purpose.
This publication explains the weight-area method, one of the two methods in which solid or semi-solid applicators can be calibrated. Proper calibration is required by law.

This publication discusses the Realistic Yield Expectations database as a resource for nitrogen fertilization rate decisionmaking. Topics include recent research and the resulting updates to the database for improved nitrogen fertilizer rates based on new yield data.
This training program is designed to provide operators of animal waste management systems with the basic understanding needed to operate and maintain these systems in an efficient and environmentally sound manner. This manual is not intended to provide all of the technical details for the complete design of a waste management system or an approved animal waste management plan.
