What biologicals do you want evaluated in soybean?


Purdue Soybean Extension will be evaluating 15 biological products in 2023 growing season, but there are nearly 100 products on the market. We want your input to determine which biologicals are of most interest to you to direct our evaluation. We have divided the biologicals into five categories: N Suppliers (non-rhizobial), P Suppliers, Humic/Fulvic Acids, Marine Extracts, and Combinations. We have a summary table for each category as well as the direct link to the company website describing that product to assist you in your selections.

Thank you for your time and consideration. We are also grateful for the support of Indiana Soybean Alliance to conduct this research.
