Abstract:

Soils are an important pool of active carbon and tillage can lead to carbon emission from agricultural soils. This study aimed in assessment of quantity of CO2 release from red loam, the major soil of Kerala under different tillage practices (conventional, with cultivator and with rotovator) and to optimize the tillage practices with minimum CO2 emission. The CO2 emission from soil surfaces were measured using base trap method with NaOH as base. The influence soil temperature, soil moisture content, organic matter in soil, soil pH, bulk density, atmospheric temperature and relative humidity on CO2 emission were assessed. The conventional tillage resulted in the maximum CO2 emission followed by the tillage with cultivator and the least value was observed when tilled with rotovator. The major quantity of CO2 was released just after the breakage of soil in all kind of tillage methods and became almost equal to the undisturbed condition after two hours of ploughing. The bulk density of soil was negatively correlated, organic carbon content was positively correlated, soil temperature was positively correlated and atmospheric temperature was positively correlated with CO2 emission from the red loam soil in all the tillage practices. No significant correlation was obtained between relative humidity and soil moisture with CO2 emission. Tillage with rotovator contributes the minimum CO2 to atmosphere and significantly affects the concentration of CO2 in the atmosphere, ultimately contribute in mitigation of global warming.
