applications

Fertilizer - When applied as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium.
Demetallation - Used oil invariably contains soluble and insoluble metal-bearing compounds. The presence of these compounds complicates the recycling of used oil as a fuel. Demetallating a used oil before its burning minimizes maintenance problems. DAP aids water dispersion throughout this process.
Control precipitation of alkali-soluble and acid-insoluble colloidal dyes on wool
Used as a yeast nutrient in winemaking and brewing mead In purifying sugar

As a Flux for soldering tin, copper, zinc and brass

DAP also acts as a fire retardant
