TERI Sees Up To 50% Drop In Chemical Fertilisers Use

DESPITE SLOW OFFTAKE of nano-fertilisers such as urea and diammonium phosphate (DAP) after their launch four years ago, application of these soil nutrients directly along with conventional applications could lead to up to 50% drop in chemical fertilisers usage over the medium term, a senior official with TERI said.

"The dose of conventional fertiliser is reduced by 25% to 50% through foliar application or spraying nano particles directly onto plant leaves for efficient absorption.

"This essentially means that only a part of conventional fertiliser is substituted by nanofertilisers," Pushplata Singh, director, centre for nano research area and agricultural biotechnology area, TERI, told FE.
