Product Description

DAP Industrial /food grade Diammonium Phosphate 52-21-00
 
 
1.Description of DAP
DAP is a product with high solubility in water,which ensures a rapid response to fertilization.As reaction fertilizer in the soil around a granular acidicication is generated that improves the utilization of phosphorus applied and available in the rhizosphere.Due to its nitrogen content(present as annonia),it is good for crops that require these nutrients in its initial phase.

2.The advantages of DAP
Fully water-soluble
Consists of 100% plant nutrients
Highly-concentrated source of phosphorus and nitrogen (as ammonia ) for plants
Free of chloride, sodium and other detrimental elements for plants
Excellent for low pH or alkaline soils
Suitable for the fertigation, foliar application and production of fertilizer blends and nutrient solutions
 
Compared with MAP:
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. DAP is alkaline with a high pH, exceeding 7.5. DAP is excellent for low pH or alkaline soils.
