Donghui Ammonium Sulfate and Ammonium Phosphate Anti-Caking Series
Fertilizers such as ammonium sulfate and ammonium phosphate are typically highly acidic and, under most conditions, do not tend to cake. However, once caking does occur, it often becomes difficult to address. Due to their inherent properties, adding conventional, general-purpose anti-caking agents fails to solve the problem. Based on the specific characteristics of ammonium sulfate and ammonium phosphate fertilizers, Donghui has developed specialized anti-caking agents for these fertilizers, ensuring that no caking will occur for up to six full months after addition.
