Product Description
Diammonium Phosphate(DAP) is a product with high solubility in water, which ensures a rapid response to fertilization.As reaction fertilizer in the soil around a granule acidicication is generated that improves the utilization of phosphorus applied and available in the rhizosphere. Due to its nitrogen content ( present as ammonia), Diammonium phosphate(DAP) is good for crops that require these nutrients in its initial phase.
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.
As dissolving DAP granules release ammonium, the seedlings and plant roots nearest the volatile ammonia can be harmed. This potential damage more commonly occurs when the soil pH is greater than 7, a condition that often exists around the dissolving DAP granule. To prevent such damage, users should avoid placing high concentrations of DAP near germinating seeds.
The ammonium present in DAP is an excellent N source and will be gradually converted to nitrate by soil bacteria, resulting in a subsequent drop in pH. Therefore, the rise in soil pH surrounding DAP granules is a temporary effect. This initial rise in soil pH neighboring DAP can influence the micro-site reactions of phosphate and soil organic matter.
As a high concentration nitrogen and phosphorus compound fertilizer, it is a kind of high efficiency fertilizer widely used in vegetables, fruits, rice and wheat.
For industrial grade,It can be used as a flame retardant and Used in rubber
