水溶性聚磷酸銨憑借以下優點進入液體肥料生產領域,并已在歐美等發達國家廣泛應用:
4、肥料施入土壤中,聚磷酸銨中的正磷酸根會先被植物吸收利用,土壤的理化性質會使聚磷酸根逐漸分解,慢慢變為正磷酸根提供植物利用,因而肥料具有緩效作用。

Water-soluble ammonium polyphosphates enter the field of liquid fertilizer production by virtue of the following advantages, and has been widely used in Europe and America and other developed countries:
1. It is a high concentration fertilizer containing nitrogen and phosphorus required for crop growth;
2. The fertilizer is neutral and has high safety and improvement to soil and crops;
3. It has good chelation to metal ions, and can add some trace elements to improve fertilizer efficiency;
4. When fertilizer is applied to the soil, the orthophosphate root in ammonium polyphosphate will be absorbed and used by plants first. The physical and chemical properties of the soil will cause the polyphosphate root to gradually decompose and gradually become orthophosphate root for plant use, so the fertilizer has a slow effect.
