Abstract
An understanding of the dynamics of soil organic carbon (SOC) as affected by organic practices is imperative for maintaining soil productivity and mitigating global warming. The objectives of this study were to investigate the effects of long-term organic practices on carbon pools was undertaken during 2018-19. The 32 soil samples were collected from certified organic and fertilized vegetable growing farmers field of selu and chinchabhavan village of Nagpur district from surface (0-15 cm) and sub-surface (15-30 cm) depth. The very labile carbon was recorded from 0.71 - 1.32 g kg^-1 and labile ranges between 0.53 – 1.01 g kg^-1, less labile varied from 0.47- 0.91 g kg^-1and non labile is highest in fertilized vegetable crop in between 4.12 to 5.62 g kg ^-1. Active pools are highest in FYM, Jivamrit, Ghanjivamrit and passive pool are found abundant in inorganic sources used. Active pool contributes 24.10% and passive pool were 75.96%. Thus the study shows that nutrient addition through organic sources can improve active carbon pool in soil.
