Effects of agricultural practices on ecosystem carbon storage have acquired widespread concern due to its alleviation of rising atmospheric CO2 concentrations. Recently, combining of furrow-ridge with plastic film mulching in spring maize ecosystem was widely applied to boost crop water productivity in the semiarid regions of China. However, there is still limited information about the potentia...

The paper discusses land surface processes in a climate model, linking the roles of hydrology, ecosystems, and carbon cycling. The integrating factor is the movement of water and carbon dioxide through the stomates of leaves. This molecular gas transfer is a major control of coupling between land and the atmosphere, as required for modeling climate variability and change, land storage of carbon...

 Background: The biogases are the mixture of gases produced through the microbial decomposition of organic waste which are amply observed in the landfills. The main purpose of this study was to estimate the emission rates of landfill gases such as carbon dioxide, methane and non-methane organic compounds (NMOCs) in the solid waste landfill of Rodan city in Hormozgan province. Methods: A...

elevated atmospheric carbon dioxide and other green house gases have increased the earth temperature in recent century, which it affects all biochemistry cycles in soils. to examine the effect of atmospheric co2 concentration and temperature on n forms in soil solution in a calcareous soil, an experiment was conducted in a completely randomized design with factorial arrangement in the laborator...

The purpose of this experiment was to determine how respiration of soybeans may respond to potential increases in atmospheric carbon dioxide concentration and growth temperature. Three cultivars of soybeans (Glycine max L. Merr.), from maturity groups 00, IV, and VIII, were grown at 370, 555 and 740 cm$ m−$ carbon dioxide concentrations at 20}15, 25}20, and 31}26 °C day}night temperatures. Rate...

At deep-sea vent systems, hydrothermal emissions rich in reductive chemicals replace solar energy as fuels to support microbial carbon assimilation. Until recently, all the microbial components at vent systems have been assumed to be fostered by the primary production of chemolithoautotrophs; however, both the laboratory and on-site studies demonstrated electrical current generation at vent sys...

A simplified procedure (involving disruption in sorbitol-pyrophosphate mixtures) permits the separation of spinach chloroplasts which retain the ability to catalyze the photosynthetic assimilation of carbon dioxide and its associated oxygen evolution.
