Scope and Purpose

The Fertilizer Expert Group will work to develop short-term, interim resolutions to fertilizer data concerns before moving forward with CAST 2021 as well as long-term resolutions for Phase 7 model. This will entail answering the following questions:

  • Are there other data sources that can inform Phase 6 nutrient application rates?
  • At what scale are inorganic fertilizer data available?
  • What is the feasibility of collecting more relevant jurisdictional level data?
  • Are there streamlined methods of tracking and reporting without undue burden on the local and jurisdictional agencies?
  • What improvements in nutrient data and application can we recommend for Phase 7?
