Growing Season Carbon Dioxide Exchange in Flooded Non-Mulching and Non-Flooded Mulching Cotton
There is much interest in the role that agricultural practices might play in sequestering carbon to help offset rising atmospheric CO₂ concentrations. However, limited information exists regarding the potential for increased carbon sequestration of different management strategies. The objective of this study was to quantify and contrast carbon dioxide exchange in traditional non-mulching with f...
متن کاملEvaluating the effects of energy and economic growth on Carbon dioxide emission (using spatial panel data)
Energy is one of the most important inputs in production. Energy usage and energy diffusion of fossil fuels in process of production cause greenhouse gases (CO2) emission and destruction of environment. According to the importance of issues like energy usage and economic growth, this paper, concerning the effects of proximity, evaluates the effects of energy usage and economic growth on emissio...
متن کاملShrub Effects on Carbon Dioxide and Water Vapor Fluxes Over Grasslands
Temperate grasslands are a species-rich ecosystem that may be important in mitigating the increase in atmospheric CO2. The effect of shrub invasion on CO2 fluxes in Northern Great Plains grasslands is not known. The objectives of this research were to determine CO2 and water vapor fluxes over a grazed mixed-grass prairie (prairie site) and a mixed-grass prairie that has extensive invasion of sh...
متن کاملSpatial and Temporal Variations in Temperate Forest Soil Carbon Dioxide during the Non-growing Season
In the Whitehall Forest of Georgia during the 1985-86 non-growing season soil CO, varied with soil depth, varied spatially at constant depth, and varied temporally with changing environmental conditions. Variations with depth in the upper 1.4 m of the soil were of greater magnitude than temporal variations and spatial differences at 30 cm depth were of lesser magnitude. Mean soil CO, in evergre...
متن کاملDiurnal patterns of gas-exchange and metabolic pools in tundra plants during three phases of the arctic growing season
Arctic tundra plant communities are subject to a short growing season that is the primary period in which carbon is sequestered for growth and survival. This period is often characterized by 24-h photoperiods for several months a year. To compensate for the short growing season tundra plants may extend their carbon uptake capacity on a diurnal basis, but whether this is true remains unknown. He...
