Sustainable Dairy Cropping Systems: The Virtual Dairy Herd

An interdisciplinary team of Penn State and USDA-ARS researchers are evaluating a Sustainable Cropping System to test the hypothesis that a dairy farm can minimize off-farm inputs and environmental impacts, and be productive, profitable and sustainable. Established in 2010 at the Penn State Agronomy Research Farm, the farm produces grain, forage and tractor fuel at 1/20th the scale of an average sized Pennsylvania dairy of 240 acres. The farm includes two diverse 6-yr crop rotations that include manure injection, perennial legumes, cover and green manure crops; a cover crop roller, winter canola, and a straight vegetable oil tractor. Within each crop rotation two management practices for no-till crop production are compared. For more: http://www.extension.org/67614
