At our final event of the year, one underlying theme was mentioned by all our speakers. To be successful with cover crops, the first step is to determine what your goals are. From there you can determine which species, seeding methods and termination plans are best suited for your operation.
Sioux County farmers Micah and Josh Rensink have been using cover crops since 2016 and have seeded them using a Hagie into standing crops, aerially into standing soybeans and drilling after silage harvest for neighbors with livestock.
“Our main goals are to reduce erosion, build organic matter, hold nutrients and reduce our herbicide use,” noted Josh. “We have looked a different mixes and seeding methods to find what will work best for us. While we don’t have livestock in our operation, cover crops provide a wide range of forage options. That is one way to help with the economics side of cover crops.”
Based on their experiences and those they worked with Micah had some great advice, “Be sure to know the seed source and quality before seeding to avoid potential weed contamination and future frustration. Cheaper seed isn’t always a better deal!”
When asked what advice they would give to first time cover crop users they stated, “Start small and start simple. Get cover crops on acres going to soybeans and give it a try. Reach out to those around you trying it. We would be happy to chat with you, too.”
Joel DeJong, ISU Extension Field Agronomist, also had some great tips to share to help align cover crops with producer goals:
- After September 15 – seed a winter small grain (rye, barley, wheat, triticale).
- Be sure to check the herbicide labels for grazing restrictions and modify herbicide plans as needed to ensure legal forage use.
- Utilize resources like the Midwest Cover Crop Council Selector Tool
- Available cost-share for cover crops ≠ goal – ask yourself “What do I want to get from using cover crops” instead.
Don’t be afraid to think outside the box, like the group of Dordt University students who wanted to experiment with interseeding and built their own custom seeder (below). Look forward to more cover crop trials and results from Dordt University students in the near future!
