Description
As the core of our product line, our latest crystallizer system helps refine high-quality ammonium sulfate and increase the production of larger Size Guide Number (SGN) particles—setting a new standard for efficiency. N-Rich 21-0-0 is the preferred nitrogen source for rice, wheat, pasture, and row crops, especially in sulfur-deficient soils. This product is optimal in areas with high pre-existing levels of phosphorus and potassium and is safe for use on lawns, gardens, flowers, shrubs, hedges, and trees.
