SUL4R-PLUS Resources
SUL4R-PLUS Comparison Chart
What Does This Mean for Farmers?
Our fertilizer is proven to show superior sustained release of sulfate over a 60-day evaluation, which matches your crop intake needs.
There’s more SUL4R-PLUS crop nutrient sulfate to be released in the soil solution even after 60 days.
ElementalS didn’t release sulfate in adequate amounts to meet crop intake needs during the 60 days, while AMS released nearly all of it in the first 10 days..

SUL4R-PLUS Rate Of Release
SUL4R-PLUS continuous release pellets maximize nutrient pull
SUL4R-PLUS is the patented calcium sulfate based fertilizer that helps yield the fullest potential for crops. This chart demonstrates the sulfate release timing of SUL4R-PLUS and alternative products on the market when compared to the nutrient uptake for corn. As indicated, SUL4R-PLUS product’s sulfate release curve most closely matches the uptake curve of corn (and most crops per study by Texas A&M) when compared to the market alternatives.
