This document summarizes the results of a test on the effects of using a structuring device on a biological/mineral fertilizer for corn production. The test measured corn moisture content and yield for different fertilizer treatments, including Infusion, Enagized Infusion, Structured Infusion, PKS & Ca, Enagized PKS & Ca, and Structured PKS & Ca, finding that the structured fertilizer treatments produced the highest corn yields of up to 208.89 bushels per acre. The test was conducted in northwest Iowa on a corn variety planted in May and harvested in October 2010.
