DAP

Diammonium Phosphate (DAP) is what’s referred to as an “ammoniated” phosphate product because the use of ammonia during the production process provides nitrogen, as well as phosphate, content. DAP, at 46 percent phosphate and 18 percent nitrogen, can be applied by itself or easily mixed with nitrogen and/or potash fertilizers, often as part of a total N-P-K (nitrogen, phosphate, and potash) plant food mix. As a granular product, DAP can be applied directly to the soil using conventional spreading equipment.
