Integrating livestock into crop rotations creates a synergy that benefits both enterprises through nutrient cycling, weed suppression, and diversified income. Grazing cover crops and crop residues converts low-value biomass into high-value animal products while improving soil biology. This time-tested approach is gaining renewed interest as farmers seek more resilient and profitable systems.
Grazing cover crop mixtures in fall and early spring provides high-quality forage at low cost while still delivering soil health benefits. Multi-species mixes of cereal rye, crimson clover, and turnips offer diverse nutrition for cattle. Managed grazing on cover crops can generate $30-60 per acre in forage value.
Limit grazing to avoid removing more than 50-60% of above-ground biomass. Leaving residue protects soil and maintains cover crop benefits for the following cash crop.
Cornstalk grazing is one of the most economical winter feeding strategies for beef cattle. Cattle selectively graze husks, leaves, and dropped ears first, providing a diet that meets maintenance requirements for dry cows. Stock at approximately 1 cow per acre per month for 60-90 days after harvest.
Livestock convert crop residues and cover crops into manure, which returns nutrients to the soil in plant-available forms. A 1,200-lb beef cow deposits approximately 70 lbs of nitrogen, 20 lbs of P2O5, and 55 lbs of K2O per year through manure and urine. This natural nutrient cycling reduces purchased fertilizer costs.

Use rotational grazing to limit time on any one area. Research shows that moderate, well-managed grazing on crop fields does not cause yield-limiting compaction in most soil types.
