Fertiliser Use Efficiency in Indian Agriculture

Vidya Sagar Recent studies observe continuing decline in fertiliser response through the 1980s. This they attribute to over- concentration of fertilisers in agriculturally advanced regions. This article, by examining fertiliser responses under field conditions, argues for the contrary. According to it, it is the low fertiliser application combined with low to very low use efficiency in the less developed regions that is primary responsible for the decline.
