It has been suggested that different pools of soil organic carbon (SOC) in agricultural lands are more effective in indicating soil quality parameters than total soil organic carbon (TOC) content. Diverse physiographic conditions of Barak Valley part of North East India has evolved diverse rice farming management practices for e.g. rainfed lowland rice, upland or dry rice (mountains and plateaus), boro rice (summer rice grown in shallow areas of wetlands) and flood prone semi deep water rice. The objective of the study was to investigatehow different pools of SOC are affected by rice farming practices based on landscape positions and also to identify the best rice management practices in terms of soil sustainability and productivity through SOC pools from short term on-farm fertilizer experiment in lowland rainfed condition. Study revealed rice farming systems influence the different pools of SOC and, therefore, can be an important tool for classification in terms of soil C sink management. Study further revealed the integrated use of organic with inorganic fertilizer enhances the productivity and appreciable increase in SOC over control treatment. Present study confirmed CVery Labile, CLabile or CActive Pool is the important determinant of rice yield over TOC.
