DAP (diammonium phosphate) fertilizer is hardly soluble in water for fertigation and phosphorus is considered as immobile element when applied in the field crops. Due to slow release and delay in most cases DAP used as basal application at the sowing time in most cases especially in the major crops. DAP when dissolved in water, works more efficiently than broadcast or soil incorporation. Most farmers use a crude method to dissolve DAP in the water for the purpose of its application along with flood irrigation. What is that? They use drop by drop of Sulphuric acid (H2SO4) @ 2 kg/50 kg bag of DAP.
Chemical department of NFC (National Fertilizer Corporation) Faisalabad has prepared a professional solvent for this purpose. 100 gram product is available in Rs.200 for speedy dissolution of DAP fertilizer. DAP is a costly fertilizer, the split application of this fertilizer can be made easy and economic through the use of solvent. 40-50% saving of DAP fertilizer may be achieved through its split applications but after dissolving well in water.
