To determine what effect different closing wheel types have on plant emergence and yield. Unfavorable planting conditions were targeted for this study.

We intentionally planted this no-till plot in less than ideal conditions. We ran into small, wet pockets where all of the closing wheels had issues closing the seed furrow.

There was an obvious advantage with the more aggressive closing wheels over the standard rubber closing wheel system.

The increased seed-to-soil contact translated into a more even stand establishment and ultimately, higher yields.
