Maine Bulletin No. ME 450-13-5
January 4, 2013
Subject: TCH – Section IV of eFOTG
Purpose. Announcing revisions and additions to Section IV – Conservation Practices of eFOTG.
Expiration Date. September 30, 2013
The Nutrient Management Conservation Practice Standard (Code 590) has been changed to align with the National Conservation Practice Standard and NRCS Nutrient Management Policy.
A Nutrient Management Specification Guide Sheet (Code 590) and a Phosphorus Index have been added to eFOTG. The Nutrient Management Job Sheet and Statement of Work (Code 590) have undergone revisions to align with the conservation practice standard.
Significant Changes and Additions
Nutrient Management Conservation Practice Standard (Code 590)
Emphasis on the “Four R’s” of current industry standards: Right placement, Right amount, Right timing, and Right source of nutrients.
Where Water Quality is a Resource Concern, soil loss must be brought down to Quality Criteria, which is “T” for each soil. Where this not possible, site-specific mitigating practices may be used to protect the resource.
Maine NRCS now requires Modified Morgan extract method for all soils tests used for Nutrient Management Conservation Practice Standard (Code 590) and for Comprehensive Nutrient Management Plans. Note: Producers must specifically request this method when sending soils tests to labs other than the University of Maine Analytical Lab.
Requires use of a Leaching Index for Nitrogen.
Requires use of a Phosphorus Index .
Nutrient Management Specification Guide Sheet and Leaching Index (Code 590)
Appendix was removed from the end of the conservation practice standard, and a Specification Guide Sheet was created. The Leaching Index is included in this document.
The Phosphorus Index (Excel spreadsheet) for Maine replaces the N&P Matrix. This document was created in collaboration with State partners and in accordance with NRCS policy and National Instruction. This P Index is to be used for all nutrient management and conservation nutrient management planning to determine the limiting nutrient. The score determines how Phosphorus may be applied.
