Establishing cover crops in South Dakota's semi-arid, frigid soils can be challenging. Viable options for timing include following wheat, in-season following the annual crops weed-free period, and in the fall following harvest. Benefits from cover crops may include: 1) reduced wind and water erosion, 2) reduced nitrate leaching, 3) increased soil organic matter and water infiltration, 4) improved nutrient recycling, 5) improved water quality, 6) improved soil health, 7) enhanced weed suppression, 8) remediation of saline and sodic soil problems, and 9) increased forage for livestock and wildlife.
Cover Crop Recipes

One of the most important attributes that cereal rye possesses over other winter cereals such as winter wheat or triticale is its tolerance to extreme cold temperatures.
mccc 135 - Post small grains, going to soybean or corn: use a cool-season mix
Planting a cover crop blend that predominantly consists of cool-season species and is winter-killed adds diversity and provides soil armor through summer and spring.
