The Cool Farm Tool model used to estimate emission of GHGs (Green House Gases), integrates several globally determined empirical GHG quantification models. Using the tool, GHG fluxes (carbon-dioxide and methane), moisture and heat in the soil-plant-atmosphere systems were measured in rice-wheat rotation. Among the cropping systems, maize-wheat cropping registered highest carbon management index. The cumulative seasonal methane emission was reduced by 75 per cent in aerobic rice as compared to continuously flooded rice and the seasonal emissions were lower in slow-release N fertilizer.
