The fertilizer effect of Best Calcium Metaphosphate CaO6P is relatively slow but long-lasting. Although it is insoluble in water, it can be gradually hydrolyzed in water and absorbed and utilized by crops. Generally, it is ideal for use as a base fertilizer, and its fertilizer efficiency is basically close to 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. Its application technology 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.

Best Calcium Metaphosphate CaO6P This fertilizer is currently produced in relatively small quantities both abroad and domestically, but it is one of the noteworthy development directions because of its high content of available phosphorus.
