Kirsten Workman and Quirine Ketterings
July 2022 brought three important updates for farmers and nutrient management planners. In particular, they will impact Concentrated Animal Feed Operations (CAFOs) and Comprehensive Nutrient Management Plans (CNMPs).
- New York State Department of Environmental Conservation released a new ECL SPDES General Permit for Concentrated Animal Feeding Operations (CAFOs) – Permit No. GP-0-22-001. This permit will replace the current ECL CAFO General Permit GP-0-16-001.
- The foundational nitrogen fertility guidelines for field crops in New York have been updated. This new document replaces the earlier version which was released in 2003. Over the past 20 years, additional research has focused on including more crops, new rotations, and reviewing and updating of guidelines and book values for yield indices.
- The foundational phosphorus fertility guidelines for field crops in New York have also been updated. This new document replaces the earlier version which was released in 2003.
