Abstract
Our study evaluated the status of phosphorus balance on Virginia dairy farms and identified management risk factors associated with those farms that had excessive phosphorus. There was no direct link between phosphorus balance and milk production, and therefore some Virginia dairy farmers efficiently balanced phosphorus without affecting the production of milk. Farms that fall outside the feasible zone of operation can improve phosphorus balance by changing management practices.
