STAC Nutrient Management Subcommittee

The national Nutrient Management (590) Standard was reviewed and updated in 2012. 

NRCS Washington (NRCS-WA) used a subcommittee to the STAC to ensure that NRCS heard state level input for possible incorporation into the nutrient management practice. NRCS has considered comments from the STAC Subcommittee and finalized the standard.

  • The standard will be posted on Feb. 18, 2014 on the eFOTG
