Fall fertilizer applications can free up time in the spring and can offer savings on fertilizer cost from earlier purchases. When looking for fertilizer options, Smart Nutrition™ MAP+MST® offers growers unparalleled phosphorus and sulfur nutrition suitable for both fall and spring applications to meet crop sulfur and phosphorus needs.
Below shows average corn yield from independent researchers showing the importance of sulfur nutrition for maximizing yield potential. Sulfur sources and MAP were applied in the fall or spring as ammonium sulfate (AMS) with MAP, or Smart Nutrition™ MAP+MST® (average of 9 site-years in the US Corn Belt (IN, IA, KS) from 2018-2022). All nutrients balanced except the control which did not receive sulfur.
With the current US price of corn at $4.76 and a 10 bu/ac increase with MAP+MST®, the gross return for this would be $47.60/ac, showing the benefit of balanced fertility, including sulfur as MST®. Ask your retailer about MAP+MST® for your 2024 fertility program.
