Quantifying greenhouse gas emissions from soils: Scientific basis and modeling approach
Global climate change is one of the most important issues of contemporary environmental safety. A scientific consensus is forming that the emissions of greenhouse gases, including carbon dioxide, nitrous oxide and methane, from anthropogenic activities may play a key role in elevating the global temperatures. Quantifying soil greenhouse gas emissions is an essential task for understanding the a...
متن کاملModeling impacts of carbon sequestration on net greenhouse gas emissions from agricultural soils in China
[1] Soil organic carbon (SOC) contents in many farmlands have been depleted because of the long-term history of intensive cultivation in China. Chinese farmers are encouraged to adopt alternative management practices on their farms to sequester SOC. On the basis of the availability of carbon (C) resources in the rural areas in China, the most promising practices are (1) incorporating more crop ...

متن کاملGreenhouse Gas Emissions from Livestock and Poultry
In 2008 the Environmental Protection Agency (EPA) estimated that only 6.4% of U.S. greenhouse gas (GHG) emissions originated from agriculture. Of this amount, 53.5% comes from animal agriculture. Agricultural activities are the largest source of N2O emissions in the U.S. accounting for 69% of the total N2O emissions for 2009. In animal agriculture, the greatest contributor to methane emissions ...
