Use of fertilizers in conjunction with organic
manures, biofertilizers, etc. on the principle of integrated nutrient supply
system is a right prescription to increase nutrient use efficiency, minimize
use of mineral fertilizers, and reduce GHG emissions. Use of nitrification
inhibitors will regulate nitrification and leaf color chart will ensure
judicious use of N-fertilizers, increase N use efficiency and reduce N2O
emission and also cut on the fertilizer costs, Promotion of organic farming
will arrest fertilizer use and minimize GHGs emissions.
