Integrated crop–livestock systems have included grazing perennial grasses during the spring and summer and corn ( L.) residues during the winter. Our objectives were to identify opportunities for expanded corn residue use through grazing and provide an economic assessment for value-added grazing. We estimated the economic value to the crop sector through grazing leased corn residue at over $95 million for Nebraska, South Dakota, Kansas, and North Dakota under current management. Additionally, gross economic value to the livestock sector in these states was estimated at greater than $191 million. Advantages for increased grazing use of corn residue include managing residue quantity in high-yielding environments, providing a source of supplemental revenue, and expanding integrated crop–livestock systems using a simple, but cost-efficient practice. |
