Meeting Soybean Fertility Needs

One goal of the Ohio Soybean Council is to make Ohio’s soybean farmers more profitable, writes Dusty Sonnenberg, CCA, at Ohio’s Country Journal. With the task of increasing soybean yields and increasing the return on investment (ROI), a number of production practices are often considered. One of those practices, often promoted by ag retailers, is the application of foliar fertilizer.


In a multi-state trial conducted in 2019 and 2020 by Emma Matcham, a PhD student at the University of Wisconsin, prophylactic foliar fertilizer was applied and evaluated.

“A prophylactic application means that in the trial we were applying fertilizer before there was noticeable nutrient deficiency expressed in the crop,” Matcham said. “For this research, 46 trials were conducted in 16 states across the eastern half of the U.S. Some of the products included macronutrients such as nitrogen (N), potassium (K), and sulfur (S), some micronutrients, and some products included a combination. All products were sprayed at the R3 growth stage to coincide with a fungicide and insecticide application. There were a wide variety of growing environments and average yield ranges.”
