With capacity to produce 100,000 tons of calcium sulfate fertilizer, SUL4R-PLUS opened a new plant in Marissa, Illinois.
Manufactured from by-products from coal-fired power plants SUL4R-PLUS is a patented, dust-free, low-salt, calcium-sulfate fertilizer. This is the company’s second production facility and is located near the Prairie State power plant. SUL4R-PLUS is distributed by HELM, and the Marissa plant can supply up to 2 million crop acres.
“Our commitment to innovation is somewhat unique in the fertilizer industry, but we believe new developments in crop nutrition can help support the need for farmers to produce more,” says Terry Gill, SUL4R-PLUS president and CEO. “It’s important that farmers have cutting-edge crop nutrition products to match the innovation in their seed and crop protection products. Farmers who have used SUL4R-PLUS are seeing the crop yield and environmental benefits, and it has led to strong demand.”
SUL4R-PLUS is a slow release granular product providing sulfur, calcium and fulvic acid and is designed for use in soybeans, corn, small grains, alfalfa, forages, fruits or vegetables.
“Our team is committed to bringing innovative solutions to ag retailers and their growers as they look to increase crop production and nutrition,” adds Gill. “This new location is one physical example of our dedication to the future of agriculture here in the heartland.”
