Farm Storage Facility
Food
Farm is a 200-acre community-supported agriculture farm located in Wrenshall,
Minnesota. It has 100 summer vegetable shares, 36 winter vegetable shares,
pastured poultry, and egg shares. The farm is run by John Fisher-Merritt
and his family according to the biodynamic philosophy. The farm also wholesales
certified organic vegetables to the Whole Foods Co-op in Duluth.
Food Farm installed
automatic temperature control and a monitoring system in their rootcellar.
Food Farm received a sustainable agriculture grant from the Minnesota Department of Agriculture (MDA) to fund this project. Read about this on the MDA website starting on page 34 in the 2004 Greenbook .
