DAP fertilizer 18/46

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.

The advantages of Diammonium phosphate(DAP)

(1)Fully water-soluble

(2)Consists of 100% plant nutrients

(3)Highly-concentrated source of phosphorus and nitrogen (as ammonia ) for plants

(4)Free of chloride, sodium and other detrimental elements for plants

(5)Excellent for low pH or alkaline soils

(6)Suitable for the fertigation, foliar application and production of fertilizer blends and nutrient solutions

Compared with MAP: The ammonium present in Diammonium phosphate(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 Diammonium phosphate(DAP) granules is a temporary effect. This initial rise in soil pH neighboring Diammonium phosphate(DAP) can influence the micro-site reactions of phosphate and soil organic matter.  Diammonium phosphate(DAP) is alkaline with a high pH, exceeding 7.5. DAP is excellent for low pH or alkaline soils.
