2017 Multi-Location Corn Soil Amendment Study - Wex®

Wex is labeled as a soil amendment to help reduce soil crusting, stimulate root growth, and improve nutrient uptake. Over three years, we have observed a $6.11 average increase in return on investment leading to this product being labeled PFR Proven.

The purpose of this study is to evaluate Wex, a soil amendment product, and its ability to stimulate root development, improve water and nutrient uptake, and increase yield and profitability.

Wex® is advertised as helping to reduce soil crusting, stimulate root growth, and improve nutrient uptake. We saw stand improvements due to reduced soil crusting at our Indiana PFR site in 2015 and at our Southern Illinois PFR site in 2016, which resulted in yield increases. In 2016, we observed visual differences in root growth in Ohio, but that did not result in
increased yield. This year, we did not observe any differences in crusting or root mass, but still saw a yield increase at all locations. This suggests that this year’s yield gains were due to improved nutrient uptake.
