Water quality program

Agricultural runoff is one of the biggest contributors to non-point source water pollution. Cows on dairy farms produce large quantities of manure. In Why County, 75 percent of dairy farmers spread manure as fertilizer on fields to increase yields and meet the nitrogen needs of crops. Phosphorus is added as a nutritional supplement to animal diet to maximize milk production. The phosphorus ends up in the manure and eventually in the water supply.
