Cover crops are growing in popularity across the state as a way to reduce soil erosion and improve water quality and soil health. In central Iowa, where fall tillage is common, there has also been increasing interest in no-till — especially no-till soybeans thanks to innovative farmers like Mike Helland leading by example in Story County.
Mike hosted a field day last Thursday near Huxley to share his experiences using cover crops in his operation. While there was significant interest in the benefits of cover crops, including a credit on crop insurance, the majority of the questions and discussion was around using no-till in central Iowa where the soils tend to be heavier and wetter than other soil regions.
Mike began no-tilling soybeans in 1993 after attending the Farm Progress Show the year before. That first year the soybeans yielded better than the other fields so he decided to try it again the next year. After similar results, he began no-tilling all his soybeans in 1995.
“Tillage is one of the root causes of compaction,” stated Helland. “This year, the no-till soybean ground was holding up our equipment instead of sinking in like some of our neighbors. I love planting no-till beans – it’s such a smooth ride!”
As we headed back inside, Mike was joined by fellow farmers Aaron Lehman and Mark Kenney on a panel to discuss how they are using cover crops in their conventional, organic and seed corn operations, respectively.
“I thought there’s got to be something better than seeing the fields black, allowing soil to wash and blow away following seed corn harvest,” commented Kenney. “So we started seeding oats after harvest to protect our Century Farm. There is no natural system that leaves the soil black, so his is our effort to keep the soil protected!”
As the panel wrapped up, Helland shared this great piece of advice, “Everyone should try cover crops on 10 acres. It doesn’t cost much and who knows – you might like it!”
We have a few more field days still on the schedule, visit our events page to find one near you and RSVP today!
If you missed this field day, be sure to tune in to our webinar December 12th at Noon to learn how #NotillB4Beans and #CoverYourBeans can help save time and money.
The field day was hosted by Practical Farmers of Iowa, the Iowa Farmers Union, the Soil Health Partnership, the Iowa Seed Association, the Department of Agriculture and Land Stewardship Clean Water Initiative, Iowa Corn, Iowa Soybean Association and the Iowa Agriculture Water Alliance and Iowa Learning Farms.
