The Science
Optimal crop nutrition is more than just N, P and K. Secondary nutrients, like calcium and sulfur, are often overlooked but serve important roles in crop production, from improved plant and soil health to higher growth and yield potential.
SUL4R-PLUS provides consistent availability of these vital secondary nutrients across the crop’s life cycle. There are three ways to win with SUL4R-PLUS:
- Agronomically: Immediate calcium and sulfur availability for improved early-season stress tolerance, plus long-lasting nutrient release to end the season strong.
- Efficiently: Just one application provides season-long access to plant-available secondary nutrients to maximize yield and quality potential.
- Economically: Superior soil and plant health benefits combined with less pricing disparity reduce risk and add value compared to other commodity fertilizers.
