Abstract/Description: | Pools of organic carbon are quantified fromthe soil samples under scented rice crop from different soil layers (0–10, 10–20, and 20–30 cm) under 9 years’ long-term trials with five treatments in scented rice–potato–onion cropping system. These treatments were 100 % NPK (NPK), 50 % recommended NPK through mineral fertilizers ? 50 % N as FYM (NPK ? FYM), FYM ? vermicompost (VC) ? neem cake (NC) each equivalent to one-third of recommended N (FYM ? VC ? NC), 50 % N as FYM ? biofertilizer for N ? bone meal to substitute phosphorus requirement of crops ? phosphate solubilizing bacteria (FYM ? BFN ? BM ? PSB), FYM ? vermicompost ? neem cake each equivalent to 1/3rd of recommended N ? PSB (FYM ? VC ? NC ? PSB). SMBC (479 mg kg-1), HWEOC (373 mg kg-1), CWSCHO (235 mg kg-1), HWSCHO (839 mg kg-1), and ASCHO (180 mg kg-1) were found to be the highest in the soil treated with FYM ? VC ? NC ? PSB and the lowest with NPK. The quantity of hot water-extractable carbohydrate content is highest amongst cold water, dilute acid and hot water extractable carbohydrate that decreases with the soil depth irrespective of treatments, except CWEOC. Soil microbial biomass carbon (SMBC) shows significant correlation with CWEOC (r = 0.60 * *), HWEOC (r = 0.94 * *), CWSCHO (r = 0.75 * *), HWSCHO (r = 0.83 * *), and ASCHO (r = 0.83 * *) that primed for better aggregate stability irrespective of soil layers up to 30 cm depth. This indicates that labile carbon pools, most specifically watersoluble carbon, carbohydrate, microbial biomass, could be a suitable indicator for evaluation of soil quality, particularly in relation to soil aggregation |
