The purpose of this study is to evaluate the use of a silicon product, applied at various growth stages, and its impact on yield and profitability.

2018 Southern Illinois Soybean Silicon Study

Silicon has been found to improve standability, increase nutrient uptake, prolong flowering periods and help reduce the impact of environmental stresses to crops. The question is, at what stage is the best time to apply silicon to achieve the greatest benefit? The pre-emerge application and the V5 application both improved yields slightly, with only the V5 application yielding a positive return on investment. As you’ll notice in other studies from the Southern Illinois PFR site this year, growing conditions were very favorable. We believe that under more stressful conditions, the addition of products containing silicon may provide a greater return.
