    Plant Nutrient Oversight

    Plant Nutrient Oversight Committee Purpose, Structure, and Role

    Purpose: Provide standing authority to define and maintain the internal consistency and scientific integrity of IFAS nutrient management recommendations for Florida agricultural and horticultural crops.

     Structure:

    • Authority comes from UF/IFAS SVP, delegated to the Deans for Research and Extension as Co-Chairs. 
    • Core PNOC consists of 14 members, roughly half IFAS Administrators and half senior faculty with a nutrient management background.
    • PNOC meets as needed to conduct business using a hybrid in-person and Zoom format.
    • Sub-committees composed of nutrient management research/extension faculty will develop specific IFAS nutrient recommendations and management systems.

    Role:

    • Prioritize commodities and associated nutrients that require IFAS nutrient management recommendation changes.
    • Define the standard format for an IFAS nutrient management recommendation.
    • Develop a standard process for faculty to follow when updating IFAS recommendations.
    • Set criteria that faculty must meet to change an IFAS recommendation.
    • Evaluate faculty proposals to change IFAS recommendations, and vote to approve, return for revision, or deny.
    • Engage stakeholders in two-way communication about PNOC activities.
