Improve Crop Yields in Agricultural Operations.
Easy to use plant nutrients, delivered where they need it, when they need it. Compared to ammonium sulfate and elemental sulfur, SUL4R-PLUS® Calcium Sulfate has many substantial advantages, proven to enhance yields for your crops. Experience the benefits of our innovative, patented granular calcium sulfate.
Unlike ammonium sulfate applications and elemental sulfur, dust-free SUL4R-PLUS handles like a dream—a huge operational advantage for you. Plus, its nutrient releasing characteristics mimic the nutrient uptake curves of most crops during the growing season, making it a superior source of Sulfate-Sulfur for spring or fall application.
SUL4R-PLUS products are less sensitive to changing weather conditions than most other dry fertilizers. They have a Critical Relative Humidity (CRH) of 75% and 85%, higher than urea at 72%. Blending SUL4R-PLUS products with urea results in a slight decrease in CRH to 75%-80%, whereas most NPK blends have a CRH of 50%-55%. Our granules are uniform in size and spread evenly without gaps. In fact, New Leader© has even endorsed our patented granules.
With 21% calcium and 17% sulfur (in sulfate form), SUL4R-PLUS patented product delivers significant agronomic advantages versus elemental sulfur. The granules dissolve almost immediately after contact with moisture in the soil and the nutrients are immediately available to your plants. Nutrients continue to release in the soil solution throughout the growing season, unlike elemental sulfur, which can take a year or more for microbes to convert it into plant usable form.
Another advantage of our patented SUL4R-PLUS products is the fulvic acid content – typically 6–8% by weight. Fulvic acid is known to improve overall soil health and serves as a complexing agent to increase the uptake efficiency of other nutrients.
We’re dedicated to quality and consistency. All SUL4R-PLUS products get to the root of higher yields and leave the land better than it was.
Testimonials
97% of our soil samples (were) coming back as low to deficient in sulfur…Since using SUL4R-PLUS fertilizer, our trials have shown a better stand and healthier soybean plant early on. In three of three comparisons, it has translated to an average of 4.25 bushels/acre yield advantage where we applied SUL4R-PLUS’ patented fertilizer.”
