Diammonium Phosphate DAP is the most widely used phosphate fertiliser among growers today. It is manufactured by reacting phosphoric acid and ammonia and contains two ammonia molecules. In alkaline soil conditions, one of the ammonia molecules in DAP will revert to ammonia, making it an excellent fit for low pH or alkaline soil. DAP itself is alkaline with a high pH, exceeding 7.5.diammoniumphosphate-1418227632
