MKP

MKP is a soluble salt which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium. It is also a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, it minimizes escape of ammonia by keeping the pH at a relatively low level. It is often used as a nutrient source in the greenhouse trade and in hydroponics.

MPP Liquid

It is a special liquid mineral fertilizer that contains a high concentration of phosphorus and potassium from potassium phosphate.

View Detail →

Phosphoric acid 85%

It is Colorless, transparent and syrupy liquid; It is odorless and tastes very sour; its melting point is 42.4; it is easily soluble in water and resolves in ethanol; it may irritate human skin to cause phlogosis and destroy the issue of human body; It has relative density of 1.70(water=1)(pour 1.87),a relative vapor density of 3.38 and a saturation vapor pressure (kpa) 0.67(pour at 25);miscible in water and ethyl alcohol .

THE ADVANTAGES OF APPLYING AMINO ACID NPK FERTILIZER

The utilization rate of common nitrogen fertilizer in China is about 30%-35%. Phosphorus fertilizer is 10%-25%. Potash fertilizer is 35%-50%. In some regions, the utilization rate is even lower, which means that less than a third of the fertilizer applied to the soil is absorbed by the crop, and a considerable portion of it cannot be used and is wasted.
