Trials Continue to Show Improved Yields by Adding SUL4R-PLUS

The results are in from our 2022 corn field trials conducted in Western Kentucky! These trials demonstrated that SUL4R-PLUS can improve corn yields while also increasing nitrogen uptake efficiency and utilization by the crop. Let’s dig into the details.

The graph below illustrates the improvements we saw when compared to the farmer’s standard N-P-K application program. It demonstrated that when SUL4R-PLUS is used in your fertility program, you can not only get increased yields, but increased nitrogen utilization efficiency to further enhance grower margin per acre.

Using this combination of SUL4R-PLUS and up to 23.3% less nitrogen translated to a higher gross margin per acre in this instance. The best gross margin we found during this trial was a 15% reduction in nitrogen applied versus the grower standard and it resulted in $74.13 higher gross margin.


If you’re ready for higher yields and higher margins per acre for your growers, it’s time to consider SUL4R-PLUS. Connect with our sales team today.

  • Improve Soil Health & Crop Yields With Low Salt Fertilizer: See the Field Trial Results

    Fertilizer is an essential component of modern agriculture, providing the essential nutrients for plants to grow and thrive. However, not all fertilizers are created equal, and some can have negative impacts on soil and crop health. One factor that is often overlooked when selecting a fertilizer is its salt index, or the potential any fertilizer has to harm a crop. Excessive salt levels can lead to soil compaction, reduced water penetration, decreased plant growth, increase susceptibility to insects and disease, and reduced yields.
