Enhanced Efficiency Fertilizers – AAPFCO’s Efforts and Perspective

NRCS Nutrient Management Code 590 (May 2019) stipulates “For enhanced efficiency fertilizer (EEF) products, use products defined by the Association of American Plant Food Control Officials as EEF and recommended for use by the State LGU” (Land Grant University).  A brief overview of some of AAPFCO’s terms, policies and considerations regarding EEF’s will be presented.  Also, some of AAPFCO’s criteria regarding what qualifies as an EEF and other current activities pertaining to enhanced efficiency fertilizers and products will be discussed.  This is a rapidly evolving area, so suggestions and feedback are welcomed.
