Product Evaluation Results

Our lab offers third party evaluations of proprietary soil amendments and foliar applications aimed at improving the mineral nutrition and productivity of crops. We began evaluating products in 2015 with the goal of providing timely and valuable information on efficacy for farmers. Products to be tested target enhancing soil biological and/or chemical function. Products are most often tested on corn and soybean, applied as either a soil amendment or as a foliar application.
