Cover Crop Economics: Costs, Benefits, and Cost‑Share Programs

Cover crops are gaining attention across South Dakota as more producers look for ways to improve soil health, manage risk, and strengthen long-term productivity. Research consistently shows that cover crops improve soil structure, increase water holding capacity, reduce erosion, and help buffer crop losses during drought or extreme weather.

Cover Crop Grazing Windows for South Dakota Crop Rotations

This guide is intended for livestock producers and crop producers interested in integrating cover crop grazing into cash crop systems. Recommendations identify opportunities for both fall grazing of rapidly establishing annuals and spring grazing of overwintering species, helping extend grazing seasons, reduce harvested feed costs, and improve nutrient cycling within crop rotations.
