Agronomic Research

Having conducted on-farm research for more than 30 years, Marion has captured a wealth of data that he likes to share with other farmers with the hope that it will encourage them to do their own on-farm research and better understand ways to maximize potential yields and profits. The most recently published research booklet can be found in the link below.

2015 Calmer Ag Research Data

"We are really pleased with Calmer's Trash Reduction Row-Unit Upgrade Kit. The kit took care of every problem we had. We installed it last season and it was the first season we had without stopping once to remove trash from the corn head. We wish we had installed it years ago."
