Fertilizer

Ammonium polyphosphate has high nutrient content and good solubility, and it is not easy to react with calcium, magnesium, iron, aluminum and other ions in the soil solution to make phosphate ineffective. Ammonium polyphosphate also has the function of chelating metal ions, improving the activity of trace elements such as zinc and manganese. Due to the advantages of ammonium polyphosphate, this product is widely used in developed agricultural countries and is the main variety of liquid fertilizer. After the ammonium polyphosphate is applied to the soil, a hydrolysis reaction occurs under the action of an enzyme. The hydrolysis reaction is quite complicated because the ammonium polyphosphate solution contains several compounds such as orthophosphoric acid, pyrophosphoric acid, tripolyphosphoric acid, and more polymers, and orthophosphate is the final product of polyphosphate hydrolysis. The temperature of the soil or cultivation substrate, moisture, pH, and other factors all affect the rate of hydrolysis. However, the hydrolysis rate is generally faster and can be completed within hours to days. Generally, crops only absorb phosphorus in the form of orthophosphate, so the speed of polyphosphate hydrolysis determines the speed of phosphate fertilizer. Because part of the polyphosphoric acid is orthophosphoric acid, ammonium polyphosphate is a fast-acting and long-acting phosphate fertilizer.
