Sulf-N® fertilizers satisfy the growing need for sulfur created by clean air regulations and higher-yielding crops, and provide a more efficient form of nitrogen. Browse the university and industry research below for information on how Sulf-N® can benefit your crops.
The sulfate sulfur and ammonium nitrogen in ammonium sulfate have been proven to counteract the steady depletion of soil sulfur and increase yields in alfalfa.Canola
Canola has among the highest demands for sulfur of any commercial crop in North America.Corn
Using ammonium sulfate in a pre-plant or starter application provides essential sulfur for early season corn growth, encouraging better emergence, faster maturity, and higher yields.Cotton
Cotton requires sulfur before its first blooms to avoid yield losses, which can be as much as 12 pounds of sulfur per bale of yield.Forage Grasses
Sulfur is vital for high-yielding grasses, and contributes significantly to improved forage quality.Potatoes
The shallow root systems in potatoes are ineffective at taking up nitrogen deep in the soil.Rice
Ammonium sulfate has been shown to increase rice yields by up to 30 bushels per acre in university trials when compared with crops fertilized with urea.Specialty Crops
Ammonium sulfate delivers fast-acting, long-lasting nitrogen and immediately available sulfate sulfur to specialty crops.Wheat
Ammonium sulfate helps promote tillering and healthy root development in fall applications and a vigorous start in early spring applications.
