Products Description


 DAP is extensively used in agriculture as a high-concentration nitrogen-phosphorus fertilizer. Its balanced composition makes it suitable for promoting vigorous plant growth and enhancing crop yields. It is commonly applied to a wide range of crops, including cereals, fruits, vegetables, and oilseeds.
a. Solubility: Diammonium hydrogen phosphate is highly soluble in water, making it readily available to plants when applied as a fertilizer. This solubility also facilitates its use in liquid formulations.
b. pH Level: DAP typically has a slightly acidic pH, which can help in soil acidification, if needed, to improve nutrient availability to plants.
c. Nutrient Content: DAP is an excellent source of nitrogen and phosphorus, with a nitrogen content typically ranging from 17% to 21% and phosphorus content between 44% to 46%.
d. Compatibility: DAP can be blended with other fertilizers and nutrients, allowing for customized formulations tailored to specific crop and soil requirements.
