  • Draft Report: Alternative Technologies/Uses for Manure (PDF) (2,533KB)

  • This document is a compilation of alternative uses for manure from animal feeding operations (AFOs). This document serves as a reference concerning the use of alternative technologies to address situations where the overapplication of manure to croplands can cause excess nutrients to enter surface waters and ground water through runoff and other hydrologic processes. These excess nutrients can cause numerous water quality impacts. Utilization of these technologies may assist operators in meeting National Pollutant Discharge Elimination System (NPDES) permit requirements.
