Audited Supplier DAP is the world's most widely used phosphorus fertilizers that also contains N (18%). In 2019, the world total DAP consumption in agriculture was approximated at 17.2 mil tonnes. India is the largest agricultural consumer of DAP in the world. The leading five countries that account for 92.01% of DAP use include India, United States, Pakistan, Bangladesh, and Turkey. Pakistan's share in agricultural use of urea is around 11.81% (FAO, 2021).
The ammonium present in DAP is an excellent N source. The initial pH of DAP solution is basic and can influence the microsite reactions of phosphate and soil OM (Zhang et al., 2017). However, nitrification of ammonium (NH4+) and its uptake by plants results in a subsequent drop in pH. Therefore, the rise in soil pH surrounding DAP granules is a temporary effect. A minor portion of DAP fertilizer is being produced locally and the rest of it is imported to meet the demand of this fertilizer. The only manufacturer of this fertilizer is Fauji Fertilizer Company Ltd.
The demand and utilization of DAP fertilizer increased in Pakistan gradually, especially in the last decade. Major portion of this fertilizer is imported without substantial increase in local production capacity. Fig. 2.4 shows the local production and import of this fertilizer from 2003 to 2017. The maximum availability of DAP was in 2017 in which 809 1000 tonnes was produced locally while 1730 1000 tonnes was imported.
