While many producers concern themselves primarily with nitrogen when growing wheat, sulfur is a limiting factor for both yield and grain quality. In fact, a lack of sulfur is often mistaken for nitrogen deficiencies. Even if you have more than enough nitrogen for a robust and healthy crop, you won’t see those results unless you also have enough sulfur. With SUL4R-PLUS’s patented fertilizer formula, you’ll be sure to have all the nutrients you need for a sustained and successful growing season. However, sulfur sources are not created equal. To meet your crops’ sulfur needs, our fertilizer releases the nutrient at steady rate throughout the growing season.

Thanks to quantified field trials and many years of application on crops around North America, you can trust that SUL4R-PLUS will release sulfur to match plant needs while also recognizing the boot in your yield. In field trials from 2017, SUL4R-PLUS fertilizer provided a nine bushel (9bu/ac) per acre gain, with a 2lb per bushel better weight and 1.09% better protein than control. These results have been replicated in a new, 2021 field trial. With eight more bushels per acre than AMS and 1.38% more grain protein. Wheat that was planted with a SUL4R-PLUS application has once again has shown yield advantages compared other options.
