While India uses many types of fertilizers, urea accounts for most of the consumption of N and DAP for most of that of P2O5. Urea accounts for 82 percent of the total consumption of straight N fertilizers.

Di-ammonium Phosphate popularly known as DAP is a preferred fertilizer in India because it contains both Nitrogen and Phosphorus which are primary macro-nutrients and part of 18 essential plant nutrients. DAP (NH4)2HPO4: Fertilizer grade DAP Contains 18% Nitrogen and 46% Phosphorus (P2O5)..
DAP is generally applied as a basal dose before sowing. The Earliest seed germination is not earlier than 6 days and roots are initiated. Nitrogen does not stay in soil beyond 36-48 hrs.
