Characteristic
Diammonium phosphate is white crystal, soluble in water, stable in the air, not easy to absorb moisture, can provide plants with water-soluble phosphorus and ammonium nitrogen. It is suitable for all kinds of soil structures, especially suitable for melons, fruits and vegetables, fruit trees and cash crops, and has significant economic benefits
————————————————————————————————————————
Function
1. In is with water-soluble phosphorus and ammonium nitrogen exist, which effect fast and is long-lasting and stable;
2. It does not contain harmful substances to crops, and is suitable for foliar spraying, drip irrigation and flushing;
3. The purity is as high as 99%, fast water soluble: suitable for various irrigation and fertilization systems;
4.PH value is 7.8-8.2, which can effectively regulate the pH balance of soil and plant physiological cells
————————————————————————————————————————
Application
1. This product is a low alkaline product,which has effect on the modification of acidic soil.
2. P can improve the differentiation vitality of plant flower buds, increase fruit hardness and shelf life, so the product can also be used in the early flowering and fruitset stage of crops;It is recommended to use an appropriate amount of product mixed with water spraying or drip irrigation fertilizer.
3. The phosphorus content in the product is high and easy to be absorbed, and the effect is better when used in the early stage of crop growth.
————————————————————————————————————————
Attention
Diammonium phosphate can be mixed with other water-soluble nitrogen fertilizers and potassium fertilizers for better effect, so as to meet the nutritional needs of more plants in each growth stage. It can be mixed with neutral and alkaline pesticides, not with acidic pesticides, and can not be mixed with plant ash (the main component K2CO3), and can not be mixed with alkaline fertilizers containing calcium or magnesium, so as not to produce precipitation and affect fertilizer efficiency.

Usage&Doseage
Basic fertilizer application:60-120 kg/Acre;
Drip irrigation application: 30-60 kg/Acre, apply 2-3 times, with an interval of 10-15 days;
Foliar application: 3-6 kg/Acre with 2-5 applications at an interval of 7-10 days.
Due to the complexity of crop nutrient deficiency and fertility tolerance, as well as the different soil structures and fertility
in various places, the above usage and dosage are for reference only, and the specific dosage should be recommended by
local agricultural technicians.
