The Flats Mentor Farm (FMF, or The Flats) is located on a 70-acre river bottom parcel of land in Lancaster, Massachusetts. FMF assists and supports small farmers of diverse ethnic backgrounds with the land, farming infrastructure and marketing assistance needed to promote and sustain successful farming enterprises. FMF promotes economically viable agricultural production that protects the environment through the practice of sustainable farming methods. With the help of a farm manager, sustainability coordinator, and the entire World Farmers team, farmers at the Flats have access to shared and individual resources, as well as hands-on-training and technical assistance on soil fertility, irrigation, pest and weed management, and marketing.

Immigrant and refugee farmers have been farming at this location since 1985. In 2005, after many trials and tribulations, the farmers formally organized to become Flats Mentor Farm. Since then, with the support of Heifer International, the University of Massachusetts Amherst, the Society for the Promotion of Agriculture, the USDA, and many others, the farmers at FMF have evolved from growing enough for their immediate and extended families to selling their produce at farmers’ markets and throughout cooperative wholesales across the state. The number of farmers selling at these markets have increased each year, from just 6 farmers markets in 2005 to 40 in 2017.
