What are high phosphorus fertilizers?

Phosphorus, as a macronutrient, is not only a component of plant tissues, but also participates in many metabolic processes of plants, such as energy conversion and enzyme formation. Its importance to crops is self-evident. High-phosphorus water-soluble fertilizers are rich in phosphorus, so their main function is also related to phosphorus.

What is high phosphorus fertilizer?

Labeled with phosphorus (P2O5), it is a phosphate-based fertilizer, a unit fertilizer whose main function is to provide phosphorus nutrients to plants.

In addition to using high-phosphorus water-soluble fertilizers for traditional crops, the application of high-phosphorus water-soluble fertilizers is indispensable in many flower plantings because it can make flowers bloom more and grow stronger.

What are high phosphorus fertilizers?

According to reports, high-phosphate fertilizers contain calcium magnesium phosphate, calcium phosphate, superphosphate, monoammonium phosphate, and diammonium hydrogen phosphate . The rational use of phosphate fertilizers can increase crop yields, improve crop quality, increase crop fruiting rates, and increase crop sweetness.

1. Monoammonium phosphate

The chemical agent diammonium phosphate, also known as monoammonium phosphate, is a white crystal with the chemical formula NH4H2PO4. It can be decomposed into ammonium metaphosphate (NH4PO3) when heated.

The product can be made by reacting ammonia water with phosphoric acid. It is mainly used in fertilizers and fire retardants for wood, paper, and fabrics, as well as medicines and ruminant feed additives.

2. Diammonium phosphate

Diammonium phosphate refers to a standard product containing 18% N and 48% P2O. Its crystal form is flat-oblique prisms. Its solubility in 25C water is 71%. The pH value of its saturated solution is 8, which is much higher than that of monoammonium phosphate.
