Brief Project Summary:

Soybean yields have been gradually increasing due to genetic and management improvements. Traditionally, soybeans are grown without nitrogen fertilization. However, in high-yield scenarios, particularly under irrigation, they may not have the ability to fix or obtain enough N to maximize yields. Some of the sandy and low organic matter soils in Delaware may not be able to supply sufficient sulfur in a high-yield scenario. This project gathered local data on locally on applying supplemental N and S to irrigated full-season and double-cropped soybeans via fertigation, as farmers have reported positive yield responses to this practice at flowering, beginning pod or beginning seed fill growth stages.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
