Foliar Fertilizers

There is interest among farmers and agronomists to test different fertilizer products to improve soybean yield. We tested an array of foliar fertilizers in 46 environments across the United States. The following resources outline the results of our studies conducted independently by Science for Success team members and funded by public entities. 


Flowering marks the beginning of rapid dry weight and nutrient accumulation rates. Dr. Shaun Casteel, Extension Soybean Specialist, Purdue University explains what is happening in the soybean plant through the process of flowering (growth stages R1-R3) in this video.
