Description
Overview
Diammonium phosphate (DAP) is the world's most widely used phosphorus (P) fertilizer. It is made from two common constituents in the fertilizer industry and it is popular because of its relatively high nutrient content and its excellent physical properties.DAP fertilizer is an excellent source of P and nitrogen (N) for plant nutrition.
Features
It's highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. ... As dissolving DAP granules release ammonium, the seedlings and plant roots nearest the volatile ammonia can be harmed.
