Agricultural Research Service scientists are developing an innovative approach to address a major environmental challenge facing the nation’s animal farmers: the accumulation of nutrients in the manure.

Manure produced in livestock and poultry operations has been increasing since the 1950s when large-scale feeding operations, along with large-scale crop farms, began to replace many of the nation’s small, family-run farms that traditionally produced both crops and livestock and used the manure as fertilizer to boost crop yields.
