Material scientists and plant biologists from the University of Hyderabad (UoH) and International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI) have developed an industrially viable dry method to generate chemically stable and smaller nano-diammonium phosphate (n-DAP) fertilizer that would reduce over-dependence on chemical fertilizers. Chemical fertilizers application is critical to boosting crop productivity. one of the factors that contributed to the enhanced crop productivity is the application of chemical nitrogen (N), phosphorus (P), and potassium (K) fertilizers. However, excessive use of these chemicals over decades has affected the soil quality. Moreover, global phosphorus reserves are likely to be irreversibly exhausted in the next 100-200 years. India lacks big natural P-reserves and meets its P-fertilizers demand by importing. In this context, the research findings assume importance.
