Therefore, DAP is also an important additive in the wine making and brewing industry. However, a majority of the demand arises from the fertilizer sector. DAP as a chemical salt is used in many industries and the market for DAP can be segmented according to its applications into fertilizers, wine making or brewing, fire retardant, metal industry (as flux), and in the food industry (yeast nutrient).
Both MAP and DAP degrade into various reaction products. For example, MAP products are taramakite, dicalcium phosphate and struvite. DAP produces struvite and colloidial apatite. Both the DAP reaction products are relatively insoluble in soils except acid soils.The interaction of P fertilizer and formation of free ammonia causing ammonia toxicity increases when soil pH are high and in calcareous soils.undreds of field trials have compared MAP and DAP. For example, replicated research trials have been conducted at 42 sites the last three years in seven corn belt states. The average corn yield across all sites was 162.4 bushels per acre with MAp and 159.4 bushels with DAP.
