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 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 indicated that at initial, tillering, panicle initiation and at harvest stage, significantly the highest available micronutrients in soil were recorded with application of 100% NPK + ZnSO4 +FYM (T7). Compared to organics and inorganic sources alone (T12, T3, T4 and T5), their combinations (T7, T9, T10 and T11) recorded higher values of available nutrients in soil. The treatments T9 (50% NPK + 50% N through green manures), T10 (50% NPK + 50% N through FYM) and T11 (50% NPK + 25% N through FYM + 25% N through green manures) were on par with each other in all four seasons of study.
