What does this mean for farmers?
Importantly, SUL4R-PLUS fertilizer contains the nutrients your crops need—and releases them when your crops can use them. You know that your crops can only absorb so many nutrients at once. To overcome this issue, our fertilizer contains slow-release sulfur and calcium, meaning nutrients are available to your crops when it matters most.
Pellet strength and size are optimized for better spreading. Stronger and larger pellets minimize breakage, helping your team get the job done in the field. Plus, these pellets are more uniform in size, which makes them a great carrier for micronutrients like boron and zinc.
We add lignosulfanates to every batch of fertilizer, because:
They keep pellets strong, so they don’t fracture in handling.
They also help pellets break down upon contact with soil, since they’re water soluble.
They help keep your crops healthy!
Ammonium sulfate acidifies the soil, creating a need for 5.4 pounds of lime to match each pound of nitrogen. SUL4R-PLUS does not acidify the soil, so you don’t have to worry about the extra work or environmental impact of using lime.

In a 2021 soybean trial in Nebraska, SUL4R-PLUS fertilizer showed an average yield advantage of 3.65 bu/acre above AMS and 5.12 bu/acre over Grower Standard. It’s also more affordable per acre than AMS, giving you more bang for your buck. For even higher yields, try SUL4R-PLUS B+Z, which supplies additional nutrients to your crop making them stronger and healthier. With the addition of calcium, sulfur, boron and zinc, a 2018 soybean trial in Williamsburg IN found increased yield and gross revenue per acre versus the grower standard.
While you consider your fertilizer options over this winter, keep in mind what the science says. SUL4R-PLUS fertilizer is a reliable choice for securing higher yields. And as always, SUL4R-PLUS fertilizer has the additional benefits of being a homogeneous granule, superior spread, fulvic acid, low salt, dust free application and ease of use.
