Ammonium Dihydrogen Phosphate MAP Fertilizer Application

The product is widely used in vegetable crops, fruit crops, horticultural crops and cash crops;

As well as various soils, such as red soil, yellow soil, brown soil, yellow loam, black soil, cinnamon soil, purple soil, white loam, etc.;

It is especially suitable for dry and low rainfall areas.

Characteristics

Fast water solubility: fast water solubility, suitable for all kinds of irrigation equipment and facilities.

Green and safe: free of chlorine ions and heavy metal ions, non-polluting and non-polluting.

Fertilizer effect is obvious: P and N exist in the state that can be easily absorbed by the crop, and the fertilizer effect is rapid, lasting and stable.

Instructions for use:

This product is mixed with other water-soluble nitrogen and potash fertilizers for better effect.

Because of the high content of phosphorus, it is easy to be absorbed by crops, it is best to use it at the early stage of crop production.

This product is a weakly acidic product, which has a certain coordinating effect on the improvement of alkaline soil.

With drip irrigation, foliar spraying and other efficient fertilization methods, this product is more effective.
