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

Although silicon is not an essential nutrient for crop production, recent studies have shown that it could potentially help with nutrient availability if applied in-furrow, and with abiotic stress mitigation if applied as foliar. As you can see from this data, the in-furrow treatment showed great promise with a substantial return on investment, but the foliar treatments did not. This is only the first year of testing silicon products in PFR, but it’s a practice that may prove beneficial long-term. More testing is needed to confirm this hypothesis.
