Diammonium hydrogen phosphate is widely used in agriculture. It is used as a nitrogen and phosphorus fertilizer to supply nitrogen and phosphorus nutrients required by crops, promote plant growth, improve yield and quality. In addition, diammonium hydrogen phosphate can also be used to control phosphorus deficiency in soil, and can improve soil texture and fertility.

Diammonium Phosphate(DAP) application:

Phosphorus fertilizer is generally used as the base fertilizer. Under the same conditions, the higher the soil available phosphorus content, the lower the fertilizer efficiency. The suitable dosage range of phosphorus fertilizer for several main crops on the general phosphorus deficiency soil is: Phosphorus fertilizer (P2O5) (4-6) kg for grain crops, sweet potato, potato and cotton, peanut, rape, soybean, jute, tea tree (3-5) kg, watermelon (2-4) kg, tobacco (1-3) kg, sugarcane (6-8) kg, and fruit trees (0.2 to 0.3) kg per plant. When it is found that crops show the symptoms of phosphorus deficiency, phosphorus fertilizer is sprayed on the leaf surface to make phosphorus enter the object through the stomata or cuticle on the leaf surface. Rice, wheat and other gramineous crops can be used at 2% to 3% concentration, rape, vegetables can be used at 1% concentration. It can also use 0.25% concentration of potassium dihydrogen phosphate to spray after the dew dries in the morning or before the dew in the evening, which has a significant increase in production.
