The application of ammonium polyphosphate fertilizer

Ammonium polyphosphate fertilizer is mainly used in the agricultural field. As an efficient and long-lasting fertilizer, it has many advantages and applications.

The application of ammonium polyphosphate (APP) in agriculture is mainly reflected in its use as a fertilizer. This fertilizer has the following significant advantages:

Long term slow release:   Ammonium polyphosphate will not react with the soil. It will gradually hydrolyze into orthophosphoric acid in water and then be absorbed and utilized by crops, providing a long-term nutrient supply and improving the utilization rate of phosphorus.

High solubility:

Ammonium polyphosphate has a large solubility and can be configured with liquid fertilizers with high phosphorus content. It is suitable for making high-concentration and high-quality liquid fertilizers.

Good safety:

Ammonium polyphosphate can be applied directly, with good safety. The hydrolysis products in the soil will not cause soil acidification and compaction, and can adapt to various soils and crops.

Chelation:

Ammonium polyphosphate has a chelating effect on metal ions, which can prevent the formation of precipitation of metal impurities in the solution, which is conducive to the production of high-concentration and high-quality liquid fertilizers. ‌

Environmentally friendly and efficient:

As an environmentally friendly and efficient liquid fertilizer, ammonium polyphosphate usually has an average degree of polymerization of 2-18, is short-chain and fully water soluble, and contains a variety of ammonium polyphosphates, such as ammonium phosphate and ammonium pyrophosphate, which are suitable for preparing basic phosphate fertilizers for high-concentration liquid compound fertilizers. ‌

In summary, ammonium polyphosphate fertilizer plays an important role in the agricultural field with its long-term slow release, high solubility, good safety, chelation, and environmentally friendly and efficient characteristics. It is one of the important fertilizers for improving crop yield and quality.
