Ammonium dihydrogen phosphate

Product：Ammonium dihydrogen phosphate
CAS:7722-76-1
Chemical formula：NH₄H₂PO₄

Ammonium dihydrogen phosphate (MAP) is a kind of water-soluble, quick-acting
compound fertilizer. The ratio of effective phosphorus (P2O5) to total nitrogen
(N) content is about 5.44:1. It is one of the main varieties of high-
concentration phosphorus compound fertilizer. . As a raw material for
production, it is also the basic raw material for the production of ternary
compound fertilizer, BB fertilizer, etc., and it is indispensable.
Use range:
This product is widely used in vegetable crops, fruit crops, horticultural
crops and economic crops;
And various soil qualities such as red soil, yellow soil, brown soil, yellow
fluvo-aquic soil, black soil, cinnamon soil, purple soil, albic soil, etc.;
It is especially suitable for application in dry and rainless areas such as
Northwest my country, North China, and Northeast China.
Features:
Water dissolves quickly: water dissolves quickly, suitable for all kinds of
irrigation equipment and facilities.
Green and safe: It does not contain chloride ions, heavy metal ions, and is
pollution-free and non-hazardous.
Obvious fertilizer effect: Both P and N exist in a state that is easy to be
absorbed by crops, and the effect is rapid and lasting and stable.
Instructions for use:
This product is mixed with other water-soluble nitrogen fertilizers and potash
fertilizers for better effect.
Because the product contains high phosphorus content and is easy to be
absorbed, it is better to use it in the early stage of crop production.
This product is a weakly acidic product, which has a certain coordination
effect on the modification of alkaline soil.
Using drip irrigation, foliar spraying and other efficient fertilization
methods, the fertilizer effect of this product is more obvious.
Precautions:
This product can be mixed with neutral and acid pesticides, and must not be
mixed with alkaline pesticides.
Avoid mixing with fertilizers containing calcium or magnesium to avoid
precipitation and affect fertilizer efficiency.
Foliar spraying should be carried out before nine in the morning and after four
in the afternoon (six o’clock in summer). Please do not use it under extreme
weather (such as strong light, strong heat, heavy rain, etc.) to avoid reduced
fertilizer efficiency and even damage to crops. Harmful situations occur.
Different regions, different soils, different crops, and different crop growth
periods have different requirements for fertilizers; therefore, the specific
use needs to follow the suggestions of local agricultural technicians.
