Abstract
Burning of biomass released gases and aerosols to the atmosphere. This study aims to estimate burnt biomass, amount of carbon returned and released through open burning and potential of global warming. The ground biomass and the carbon analysis were assessed by ground based experiments. Average burnt residues were 516ฑ128, 479ฑ44 and 1,007ฑ233 g/m2 rice residues, corn residues and sugarcane leaves respectively. Burning of crop residues released carbon into the atmosphere for more than 95% of carbon in burnt biomass. Possibility of carbon that could be back to the ground was few percent by ash and around 86% by CO2. Net carbon loss to the atmosphere was 10%, 25.98ฑ10.47 gC/m2 at each crop cycle. In general, carbon content of agricultural residues is in the same range among crops so the net carbon loss can be applied with other crops.
