Agricultural Composting Program Details

Application and registration instructions

Under that exemption, any farm that wishes to compost organic materials other than those that are generated on their own farms, must register their operation with MDAR

Farm operations that qualify for an Agricultural Composting Registration with MDAR need to fill out the Agricultural Composting Registration Application Form. The compost plan submitted with the application should follow the principles laid out in our “Guide to Agricultural Composting.”

    Agricultural Composting Training

    Few more spots available for session in Pittsfield!

    MDAR is conducting a no-cost training workshop for registered agricultural composters and other farms interested in agricultural composting (larger than backyard composting). Space is limited, and first preference will be given to farms already registered in the MDAR Agricultural Composting Program. These workshops will meet the upcoming regulatory requirement for farmers who are currently registered in MDAR’s Agricultural Composting Program to attend a state approved training program in order to continue to maintain a composting registration. Topics include:

    • Principles of Composting
    • Site Selection, Layout and Maintenance
    • Compost Recipe Development
    • Monitoring, Troubleshooting, and Development of Odor Management Plan
    • On-Farm Compost Use
    • Updates to MDAR Agricultural Composting Program Regulations


    These one-day trainings will run from 9:30 am - 4:30 pm, lunch is provided. Locations and dates are:

    • February 27 - Berkshire Athenaeum, One Wendell Avenue, Pittsfield
    • March 5 - Community Harvest Project, 37 Wheeler Road, North Grafton
    • March 11 - New Entry Sustainable Farming Project, 733 Cabot Street, Beverly
    • March 19 - UMass Cranberry Experiment Station, 1 State Bog Road, East Wareham
