A balance between the nutrient inputs and the managed nutrient outputs balance was constructed for 16 Nebraska feedlots to provide insight to potential environmental risks. Substantial nitrogen and phosphorus imbalances were observed for many participating feedlots. Size of the livestock operation and the degree of integration of livestock with a cropping operations provided only limited explanation concerning nutrient balance variations observed among the feedlots. Substantially improved nutrient balances were achieved by those feedlots marketing manure nutrients to off-farm customers. A “sustainable” nutrient balance appears possible for larger feedlots actively marketing manure nutrients.
