 Maryland Agricultural Water Quality Cost-Share Program

The Maryland Agricultural Water Quality Cost-Share (MACS) Program provides farmers with grants to cover up to 87.5 percent of the cost to install conservation measures known as best management practices (BMPs) on their farms to prevent soil erosion, manage nutrients and safeguard water quality in streams, rivers and the Chesapeake Bay. Grassed waterways (pictured) planted to prevent gully erosion in farm fields, streamside buffers of grasses and trees planted to filter sediment and farm runoff, and animal waste management systems constructed to help farmers safely handle and store manure resources are among more than 30 BMPs currently eligible for MACS grants.
