dc.description.abstract | tImproved understanding of the process of carbon (C) stabilization is critical to managing emissions fromagricultural soils and optimizing crop yield. We assessed soil organic C (SOC) stability and nitrogen (N)dynamics in a long-term fertilization experiment (started in 1972) conducted at three different locationsin India (Jabalpur-Vertisol, Palampur-Alfisol and Ranchi-Alfisol). We measured soil organic C (SOC), Cpools and stocks in the treatments of no fertilization as control, inorganic fertilization as NPK and inte-grated fertilization as NPK + farm yard manure (FYM). Quantification of different SOC pools was done bya procedure of acid hydrolysis followed by a long-term (247 days) incubation study. Based on crop yieldand C storage, NPK + FYM was the best treatment for improving crop productivity and SOC sequestration.Integrated fertilization for 38 years increased SOC across sites. In the NPK treatment, additional C input(3–9 times higher) in the form of root biomass did not significantly change C pools. Application of FYMin addition to NPK enhanced the acid non-hydrolysable fraction of SOC across sites. Stability of SOC sig-nificantly influenced N dynamics in soil and the availability of N in soil is correlated with the amount ofC in the acid-hydrolysable pool (R2= 0.64, p = 0.01) but not with SOC (R2= 0.12, p = 0.01). Long-term useof chemical fertilizers did not significantly affect soil total N content. | en_US |
