A new national NRCS 590 practice standard was released in January 2012. The Wisconsin NRCS 590 practice standard must be reviewed to be in compliance with the national standard.

Custodian: NRCS

Goal: Compare the current Wisconsin NRCS 590 Nutrient Management Conservation Practice Standard (09/05) with the revised NRCS National 590 Nutrient Management Conservation Practice Standard (01/12) and utilize a facilitated team process to develop a revised DRAFT Wisconsin 590 practice standard for review by the Wisconsin NRCS State Conservationist for acceptance or acceptance with modification.

Stated Purposes of the practice standard are to: budget, supply and conserve nutrients for plant production; minimize agricultural nonpoint source pollution of surface and groundwater; properly utilize manure and organic by-products as a plant nutrient source; protect air quality by reducing odors, nitrogen emissions and the formation of atmospheric particulates; maintain and improve the physical, chemical and biological condition of the soil.

The Wisconsin NRCS 590 practice standard must include the national practice standard’s Title, Definition, and Purpose. The DRAFT practice standard produced by the team must address ALL criteria in the NRCS national practice standard and cannot be less restrictive than the national practice standard unless a variance is granted by NRCS national leadership.
