 ABSTRACT

A field experiment entitled “Carbon sequestration and soil health under long term soil fertility management in rice-rice cropping system" was carried out under field conditions during both kharif and rabi seasons of 2016-2017 and 2017- 2018 at Andhra Pradesh Rice Research Institute and Regional Agricultural Research Station, Maruteru, West Godavari district in the ongoing All India Coordinated Research Project on Long Term Fertilizer Experiment Project. The results reported that the higher passive pools (HAC and FAC) were observed in only organic plot i.e. application FYM @ 10 t ha-1 and it was significantly superior over other treatments. Application of 100 % RDF along with ZnSO4 @ 40 kg ha-1 and Application of 100 % RDF were not significant. Slow pools (POC) were observed with the application of 100% RDF in combination with ZnSO4 and FYM @5t ha-1.

Key words: Organic manures, Inorganics, HAC and FAC.
