Overview
Nano fertilizers are emerging as substitute fertilizers for soil restoration, conservation of phosphorous nutrients, and reduction the fertilizer imports. The nano Di-ammonium phosphate fertilizer (n-DAP) is conceptualized and demonstrated successfully at the lab level. The n-DAP was prepared by a novel method, cryo-milling at ARCI without altering the chemical structure, and tested for efficacy at the University of Hyderabad. The cryo-milled n-DAP with particle size 5000 times lesser but specific surface area 14000 greater than that of commercially available DAP (C-DAP) enhanced the growth of monocot (wheat) and dicot (tomato) plants. The improved agronomic factors such as higher leaf biomass, longer shoot, shorter root, and extraordinary efficacy were observed with n-DAP for 75% lesser input than C-DAP.
Key Features
