Monroe Family Farms, established in 1936 by Lester Monroe in Weld County, is one of the oldest sustainable farms in Colorado. Now run by fourth-generation farmer Kyle Monroe, the farm raises ecologically grown melons and vegetables on nearly 200 acres in Kersey, Colorado and operates the state's oldest operating CSA program, delivering seasonal produce throughout the Front Range and Denver metro area. They do not use synthetic pesticides or fertilizers. This year they are celebrating their 90th anniversary! They have been using the same growing techniques since the farm's inception.
