Is Calcium Metaphosphate CaO6P material soluble in water
Calcium Metaphosphate CaO6P material is insoluble in water. The fertilizer effect of Calcium Metaphosphate CaO6P material is relatively slow but long-lasting. Although it is insoluble in water, it can be gradually hydrolyzed in water and can be absorbed and utilized by crops. Generally, it is ideal for use as base fertilizer, and its fertilizer efficiency is basically close to heavy Superphosphate and superphosphate.
In acidic and neutral soils, the fertilizer efficiency is worse than that of superphosphate; on calcareous soils, the fertilizer efficiency is not lower than that of superphosphate; in alkaline soils, it is not as good as superphosphate.
The application technology of Calcium Metaphosphate CaO6P material is basically the same as that of superphosphate, but due to the high phosphorus content, the application amount should be less than that of superphosphate.
