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

2017 Multi-Location Soybean Soil Amendment Study - Wex®

Wex® is a multi-purpose wetting agent that we have used pre-plant as a soil amendment in PFR for the last three years. In 2015 and 2016 we saw yield gains and positive returns on investment while 2017 was a near breakeven year. We suspect that intensive rainfall events at many of our PFR locations may have moved the Wex applications too deep into the soil profile, preventing it from having a positive effect on root development and nutrient absorption. The variability we have experienced has been in a soil-applied protocol, so maybe other benefits may occur when used in post applied scenarios.
