Diammonium phosphate (DAP) is one of the most widely used nitrogen and phosphorus fertilizers for agricultural crops. It was first produced commercially in the 1940s and has played a vital role in India's efforts to boost food grain production over the past few decades. DAP contains 18% nitrogen and 46% phosphorus and provides both macronutrients needed by plants in a single granule. https://prachicmi.livepositively.com/india-s-rising-demand-and-production-of-diammonium-phosphate-dap-fertilizer/new=1
