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), it is good for crops that require these nutrients in its initial phase.

The advantages of DAP
lFully water-soluble
lConsists of 100% plant nutrients
lHighly-concentrated source of phosphorus and nitrogen (as ammonia ) for plants
lFree of chloride, sodium and other detrimental elements for plants
l Excellent for low pH or alkaline soils
lSuitable 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.
