A fertilizer dealer in Mysore, who wished not to be named, told The Hindu that there was an increase in the application of urea as it was cheaper than non-urea fertilizers. A 50-kg urea bag costs Rs. 285 while other fertilizers like Diammonium phosphate and NPK (Nitrogen, Phosphorus and Potassium) complex cost more. Diammonium phosphate is priced between Rs. 1,000 and Rs. 1,200 for a 50-kg bag and complex fertilizers are priced in the range of Rs. 935 to Rs. 1,085 a bag. “Over-use of urea harms soil fertility. The government must take steps to limit the use of urea,” he said.
