Custodian: NRCS
Goal: This technical work team will review and revise the current NRCS Conservation Practice Standard (CPS) 590 Nutrient Management. The team will focus on the following issues:
- disincentives or barriers to implementation;
- specific technical criteria for the development and implementation of nutrient management plans; and
- software tools and technical references.
The team will research, evaluate, and question the conditions for use and the outcomes of nutrient management plans. Criteria for the standard will be based on existing science, the current federal CPS 590, and state laws and regulations. The team will examine existing research, consider new technologies, propose criteria, and consider input through expert and public review, following the Full Process detailed in the SOC Technical Standards Process Handbook.
Work Team Status: Team meetings are expected to begin August 24, 2023 and will be held approximately monthly until the draft standard is completed. Details on team resources, including team meeting agendas and notes, will be posted on this website as the work develops.
Anticipated Initial Review: Mid 2025 (depending on publication of new national standard)
Anticipated Broad (Public) Review: Summer 2025
Anticipated Publication Date: Fall 2025
