Greenhouse gas fluxes in agricultural soils under organic and non-organic management
Farming practices are known to exert strong control over the soils’ function to act as sources or sinks for greenhouse gases (GHG). A recent meta-analysis based on the evaluation of 74 published long-term system comparisons provides a comprehensive data base regarding soil organic matter development (SOM) and C sequestration potential of organic systems (Gattinger et al., 2012). Furthermore, th...
متن کاملLand use changes induced soil organic carbon variations in agricultural soils of Fuyang County, China
Purpose The purpose of this study is to understand spatial and temporal variations of soil organic carbon (SOC) under rapid urbanization and support soil and environmental management. Materials and methods SOC data in 1979 and 2006, of 228 and 1,104 soil samples respectively, were collected from surface agricultural lands in Fuyang County, East of China. Land use data were also gathered at the ...
متن کاملassessment of co2 and ch4 greenhouse gasses emission from rice and wheat cultivation soils in ab-teymor area
the global temperature has increased over the past years, and international community attempt to reduce greenhouse emissions to the atmosphere. in this study the potential of some agriculture sections for emission and absorption of co2 and ch4 was examined. rice and wheat which are two strategic crops in iran were selected for this purpose and the amounts of organic carbon loss in the form of c...
متن کاملGreenhouse gas emissions from sub-tropical agricultural soils after addition of organic by-products
As the cost of mineral fertilisers increases globally, organic soil amendments (OAs) from agricultural sources are increasingly being used as substitutes for nitrogen. However, the impact of OAs on the production of greenhouse gases (CO2 and N2O) is not well understood. A 60-day laboratory incubation experiment was conducted to investigate the impacts of applying OAs (equivalent to 296 kg N ha(...
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 ...
