California Alternative Manure Management Practices Program (AMMP)

California Department of Food and Ag

Closed August 28, 2023

CDFA’s Alternative Manure Management Program (AMMP) provides financial assistance for the implementation of non-digester manure management practices in California, which will result in reduced greenhouse gas emissions.

Alternative manure management practices involve handling manure in ways that don't involve using an anaerobic digester. Currently, eligible practices for funding through AMMP include: pasture-based management; alternative manure treatment and storage (such as compost bedded pack barns); and solid separation or conversion from flush to scrape in conjunction with some form of drying or composting of collected manure.



  • The project site must be located on a commercial California dairy or livestock operation. Individuals receiving grant award funds must be located in California with a physical California business address.

  • Projects must have existing conditions in which manure is stored in anaerobic (wet) conditions (e.g. a lagoon) with a proposal to store manure in aerobic (dry) conditions (e.g., compost) to achieve reductions in methane.  

Application Instructions
