Katie Dotterer-Pyle and her husband, David, care for some 500 cows, milking 350. Dotterer-Pyle has electronic files on each of her cows which includes their birthdays, lineage, how many calves they’ve had and their medical records. Every cow also has a pedometer that tracks how much milk she produces each shift and her average daily steps. Before that show airs, Richfield Farm, of Manchester, will be featured on “Maryland Farm & Harvest,” at 7 p.m. Tuesday, Dec. 26. According to owner Ian Seletzky, the episode shows how he markets vegetables for wholesale at the Maryland Produce Hub in Jessup. Meanwhile, Mays Farming, of Upperco, recently received an award for its cutting-edge conservation and sustainability. Mays Farming was one of 12 farms honored at the Land O’Lakes SUSTAIN Farmer Recognition and Innovation Summit on Dec. 3-5. “It’s an opportunity to promote agriculture in a positive way,” owner Toby Mays told us, noting that he plants half of his 2,500 acres in cover crops every year and that cover crops allow farmers to use less fertilizer as their organic matter in the soil increases.
