The Caking Problem of Organic-Inorganic Compound Fertilizers and Synergistic Solutions
2025-03-18
Organic-inorganic compound fertilizers combine the advantages of both components, but their caking problem is more complex. Organic matter itself is hygroscopic and sticky, while inorganic salts are easily soluble and tend to crystallize. When these two components are combined, they exacerbate each other's tendency to cake. “Catalyst.” Addressing the caking problem in such fertilizers requires a coordinated approach. On the one hand, organic raw materials must undergo thorough composting to reduce their viscosity and hygroscopicity. On the other hand, after granulation, it is essential to use highly effective composite anti-caking agents that not only possess the crystal-modifying capabilities of inorganic anti-caking agents but also contain hydrophobic components capable of preventing organic matter from sticking together. Typically, surfactants need to be formulated in combination with inert powder carriers to effectively meet this dual challenge.
