Monitoring Carbon Sequestration and Greenhouse Gas Emissions from Irrigated AgroEcosystems
نویسنده
چکیده
Conventional field cropping systems have been criticized as being unsustainable because they contribute to on-farm and off-farm environmental degradation, and are often economically uncertain. Methods to increase environmental and economic sustainability are needed. There is a critical need to develop management technologies to maximize yield and crop quality yet improve environmental impacts on soil and water resources. A long-term cropping system experiment has been established to evaluate the sustainability of reduced-till, and conventional till cropping systems in irrigated rotations. The major focus of this research is to evaluate the sustainability of the irrigated production systems by measuring agronomic performance, soil quality, nutrient dynamics, soil biological activity and trace gas fluxes (CO2, N2O, CH4). One objective is to determine the mechanisms controlling carbon and nitrogen cycling and trace gas fluxes under reduced tillage in irrigated cropping systems.

Modelling of Greenhouse Gas Emissions from Wheat Production in Irrigated and Rain-Fed Systems in Khorasan Razavi Province, Iran
Agriculture has a key role in greenhouse gas emissions. As such, the present study aimed to evaluate the greenhouse gas emissions from wheat production in irrigated and rain-fed systems. The primary data were collected from 116 wheat farmers. The results showed that the total greenhouse gas emissions from wheat production in irrigated and rain-fed systems were 637.8 and 65.12 kgCO2eq, respecti...
متن کاملThe role of ruminants in reducing agriculture’s carbon footprint in North America
Owing to the methane (CH4) produced by rumen fermentation, ruminants are a source of greenhouse gas (GHG) and are perceived as a problem. We propose that with appropriate regenerative crop and grazing management, ruminants not only reduce overall GHG emissions, but also facilitate provision of essential ecosystem services, increase soil carbon (C) sequestration, and reduce environmental damage....
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 کاملNet global warming potential and greenhouse gas intensity in irrigated cropping systems in northeastern Colorado.
The impact of management on global warming potential (GWP), crop production, and greenhouse gas intensity (GHGI) in irrigated agriculture is not well documented. A no-till (NT) cropping systems study initiated in 1999 to evaluate soil organic carbon (SOC) sequestration potential in irrigated agriculture was used in this study to make trace gas flux measurements for 3 yr to facilitate a complete...
