Diammonium phosphate (DAP) is the world's most widely used phosphorus fertilizer. It's made from two common constituents in the fertilizer industry, and its relatively high nutrient content and excellent physical properties make it a popular choice in farming and other industries. DAP fertilizer is an excellent source of P and nitrogen (N) for plant nutrition. It's highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. A notable property of DAP is the alkaline pH that develops around the dissolving granule.
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.
