Abstract

Applying ammonium sulfate (AMS) to soybean is a practice that has the potential to add sulfur and nitrogen benefits for yield and agronomic potential. The goal of this study is to determine if there is a yield difference between strips applied with AMS and those without. This study is an initial design, which will determine if there is an impact of AMS. The trial is not designed to validate which component of the AMS (nitrogen or sulfur) could be causing the potential benefits. It is designed as a demonstration that could lead to potential research validation trials in the future.
