Researchers at South Dakota State University (SDSU) have been working to improve nitrogen-fixing capabilities in soybeans. The hoped-for outcome, according to Sen Subramanian, plant scientist and agronomy professor at SDSU, is an increase in soybean yields while at the same time preserving soil health. On this edition of the Soybean Pod, we talk to Subramanian about his hypothesis that natural biological nitrogen fixation can meet the soybean plant's nutrient needs later in the growth cycle. This would ensure high yields without applying synthetic fertilizers.
