Methane and nitrous oxide emissions from rice paddy fields
Recent field studies in rice paddy fields in Japan and China have shown that N2O is emitted to the atmosphere not only after the application of nitrogen fertilisers under flooded conditions but also in a period from the final drainage to submergence in the following rice-growing season through nitrification or denitrification. Those results clearly indicate that CH4 and N2O emissions in rice pa...
متن کاملOptimizing grain yields reduces CH4 emissions from rice paddy fields.
Microbial production in anoxic wetland rice soils is a major source of atmospheric CH4 the most important non-CO2 greenhouse gas. Much higher CH4 emissions from well managed irrigated rice fields in the wet than in the dry season could not be explained by seasonal differences in temperature. We hypothesized that high CH4 emissions in the wet season are caused by low grain to biomass ratios. In ...
متن کاملMethane emissions from cattle.
Increasing atmospheric concentrations of methane have led scientists to examine its sources of origin. Ruminant livestock can produce 250 to 500 L of methane per day. This level of production results in estimates of the contribution by cattle to global warming that may occur in the next 50 to 100 yr to be a little less than 2%. Many factors influence methane emissions from cattle and include th...
متن کاملEstimation of Methane Emission from Paddy Fields in Central Plain of Thailand by Scaling Technique
Since the rapid increase in atmospheric methane was recognized in the early 1980’s, paddy fields have been considered to be one of the likely and most important sources of this problem. The objective of this study is to estimate the methane emission from paddy fields with remotely sensed data and the methane flux in situ. In this paper, firstly, we developed a scaling technique to extrapolate t...
متن کاملGaseous emissions from flooded rice paddy agriculture
[1] Modification of continental land for agricultural use has increased over the last century. Atmospheric impact of this land use change has only been addressed for a few ecosystems and compounds. This paper provides, to date, the most comprehensive examination of gaseous emissions from rice paddies. We report seasonal emission ranges and integrated emission totals for 55 chemical species. Thi...
