Alternative Manure Management Program

AMMP Demonstration Projects

In 2019 and 2020, AMMP explored utilizing a portion of its appropriated grant funding for Demonstration Projects in response to recommendations from Subgroup #1: Fostering Markets for Non-Digester Projects of the SB 1383 Dairy and Livestock Working Group. There were two types of demonstration projects:

• New Technologies and Practices (NTP) would fund projects that demonstrate manure management technologies and practices not covered under the AMMP that reduce methane emissions and maximize environmental co-benefits on California dairy and livestock operations.
  • 2019 AMMP Demonstration Projects – New Technologies and Practices Request for Grant Applications
  • 2019 AMMP Demonstration Projects NTP Applicants and Award Recipients
• Advancing Practices Farmer-To-Farmer (APFF) would fund projects that showcase methane-reducing manure management practices on participating AMMP-funded dairy and livestock operations through on-farm demonstration and farmer-to-farmer education and outreach.
  • 2019 AMMP Demonstration Projects – Advanced Practices Farmer to Farmer Request for Grant Applications
  • 2019 AMMP Demonstration Projects APFF Applicants and Award Recipients
  • 2020 AMMP Demonstration Projects – Advancing Practices Farmer to Farmer Request for Grant Applications
  • 2020 AMMP Demonstration Projects APFF Applicant List

Summaries of awarded projects and results are below.

2019 AMMP New Technologies and Practices

CDFA awarded $999,994 to a project titled “Demonstration of an Advanced Manure Management System for Reducing Greenhouse Gas Emissions and Producing Valuable Products”. This project, led by the University of California, Davis, aimed to demonstrate an integrated manure management system for reducing GHG emissions and converting solid manure into high-value compost products for efficient transportation and application on crop fields. The participating dairy already employed a screen separator to remove coarse solids from flushed manure. Solids were composted during warm weather mostly for use as bedding on the dairy. However, the liquid and solid manure streams still emitted GHG during storage. The project objectives were to technically and economically demonstrate the integration of a centrifuge with screen separator, year-round production of pelletized compost, and to conduct outreach activities to demonstrate the project to dairies and crop farmers. The technical and economic performance of the system would be evaluated using on-farm measurements and modeling tools.

2019 AMMP Advancing Practices Farmer-To-Farmer

CDFA awarded $246,247 to a project titled "Regional Dairy Farmer-to-Farmer AMMP Project Tours and Awareness Outreach". This project, led by the California Dairy Research Foundation, provided information and awareness opportunities to bolster dairy farmer understanding and adoption of AMMP practices, using a combination of videos demonstrating technology, webinars, producer experience interviews, and highlight documents. In collaboration with the California Dairy Quality Assurance Program, this project produced an educational webpage to house and share the developed materials: AMMP Outreach Project
