The purpose of this study is to evaluate different biological products, applied in-furrow, and their impact on yield and profitability.

2018 Minnesota Corn Biological Study - In-Furrow

While all of the products tested in this study differ in their composition, they all are specifically formulated to increase soil biological activity. At this location, there is no doubt that there were periods of minimal biological activity as a result of saturated soil conditions this spring. Consequently, it’s not shocking to see that all of the products tested had reasonable yield increases. We observed the largest response with SabrEx® for Corn IF, which contains two strains of trichoderma fungi.
