On-Farm Composting

Green highlighted words indicate definitions and links to the glossary section.

Composting on the farm is a natural! Plant trimmings, straw, animal bedding, and vegetable culls make excellent feedstock for a compost pile. Some farmers also bring in material from off the farm, such as yard trimmings from landscapers, to give them additional feedstock. While many farmers use existing equipment, such as a front loader, to turn the compost pile, others invest in special equipment designed specifically for this purpose.

Do I Need a Permit?
While most on-farm composting operations do not need a permit, those that process more than 2,500 cubic yards of material per year are required, at a minimum, to notify their local enforcement agency (LEA) of their operation. This table on "Regulatory Tiers for Composting Operations and Facilities" may help you determine if you need to contact your LEA. Information on regulations pertaining to composting is available here.
