Abstract

The net global warming potential (GWP) of a cropping system describes net exchanges of carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4). Greenhouse gas intensity (GHGI) relates net GWP to productivity. The use of a barley cover crop was tested in a California vineyard from 2003 to 2010...

Abstract

Wetlands emit a large quantity of greenhouse gases into the atmosphere and contribute significantly to global warming. The Qinghai-Tibetan Plateau, known as the "Third Pole" of the earth, contains abundant and diverse wetlands. Due to increasing human-induced pressures such as reclamation,...

Abstract

With growing concern on climate change, agriculture has received attention over last few decades as it is a significant contributor to global warming and total greenhouse gas (GHG) emission. GHG emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) can be affected by various...

Abstract

Agricultural ecosystems are important contributors to atmospheric greenhouse gasses (GHGs); however, in situ winter emission data in saline-alkali fields are scarce. Gas samples were collected during different periods, from three rice (R1-R3) and three maize (M1-M3) fields with different soil pH...

Abstract

Long-term, year-round monitoring is essential to obtain representative estimates of methane (CH4) and nitrous oxide (N2O) emissions from agricultural systems, yet multiyear consecutive measurements of annual CH4 and N2O emissions from subtropical rice-wheat rotation systems are rare. A six-year...

Abstract

Forages are an important part of crop rotations in many agricultural systems. In Manitoba, Canada, almost 40% of the 7 million ha agricultural area is devoted to forage crops and pastures. Use of legume forages to reduce fertilizer cost to producers can improve soil quality and productivity and may ...

Abstract

Arid and semi-arid soils often show a pulse of soil greenhouse gas (GHG) emissions upon re-wetting - whether from irrigation water or rainfall. We used a laboratory incubation to elucidate interactions of salinity, biochar amendment, and simulated wetting intensity in emissions of carbon dioxide...

Abstract

Rapidly rising temperatures in the Arctic might cause a greater release of greenhouse gases (GHGs) to the atmosphere. To study the effect of warming on GHG dynamics, we deployed open-top chambers in a subarctic tundra site in Northeast European Russia. We determined carbon dioxide (CO2), methane...

Abstract

Methane (CH4) is one of the major greenhouse gases that significantly contributes to global warming. Therefore, substantial efforts are being made to reduce CH4 emissions. Paddy fields make a major contribution to atmospheric CH4 concentration because of their anoxic soil environment. Paddy field...

AbstractFull Text

Study on greenhouse gases emission and their global warming potential under different fertilizations would be the theoretical basis for establishing measurements to reduce greenhouses gas emissions. Based on a long-term fertilization experiment, greenhouses gas (GHG) emissions from black soil of...
