On the Food Security Portal, Diammonium phosphate, commonly known as DAP, is tracked as a primary phosphorus fertilizer and a cornerstone of global agricultural productivity. As a vital source of both phosphorus and nitrogen, DAP is essential for early root development, robust plant growth, and efficient energy transfer within major food crops like rice, wheat, and maize. Without adequate phosphorus, crops struggle to mature properly, resulting in severe yield losses and weakened resilience against environmental stressors.
Because phosphorus rock reserves and processing capacities are concentrated in a limited number of exporting nations, global DAP markets are highly sensitive to disruptions. The Food Security Portal closely monitors DAP price fluctuations and trade restrictions, recognizing that supply chain bottlenecks or export bans quickly make the fertilizer unaffordable for smallholder farmers. When farmers are forced to cut back on DAP usage due to high costs, soil nutrient depletion follows swiftly. This reduction in fertilizer application directly undermines harvest volumes, feeding into global food price volatility and threatening food security in vulnerable regions worldwide.
