In rice cultivation, there are controversial reports on net impacts of nitrogen (N) fertilizers on methane (CH 4) emissions. Nitrogen fertilizers increase crop growth as well as alter CH 4 producing (Methanogens) and consuming (Methanotrophs) microbes, and thereby produce complex effects on CH 4 emissions. Objectives of this study were to determine net impact of N fertilizers on CH 4 emissions and to identify their underlying mechanisms in the rice soils. Database was obtained from 33 published… 
Methane and nitrous oxide emissions as affected by organic–inorganic mixed fertilizer from a rice paddy in southeast China
PurposeThe effects of commercial compost fertilizer application on trace gas emissions are not well understood due to a lack of field experiments. The objective of this study was to evaluate the
Effect of long term fertilization management strategies on methane emissions and rice yield.
Methane emission and soil microbial communities in early rice paddy as influenced by urea-N fertilization
Background and aimsUrea is widely used in rice farming systems to improve the nitrogen (N) availability and crop yield, yet its influence on CH4 emissions remains unclear. The present study aimed to
Land use legacies and nitrogen fertilization affect methane emissions in the early years of rice field development
Abstract Methane (CH4) emissions are critical to greenhouse gas (GHG) management in agriculture, especially in areas growing rice (Oryza sativa). However, studies on CH4 emissions and the nitrogen
Effects of fertilization on microbial abundance and emissions of greenhouse gases (CH 4 and N2O) in rice paddy fields
Results indicate that application of urea significantly changed the functional microbial composition, while the influence of straw incorporation was not significant, and the correlation between CH 4 and N2O emissions and the abundance of related functional genes was notsignificant.
Greenhouse gas emissions and reactive nitrogen releases from rice productionwith simultaneous incorporation of wheat straw and nitrogen fertilizer
Abstract. Impacts of simultaneous inputs of crop straw and nitrogen (N) fertilizer on greenhouse gas (GHG) emissions and N losses from rice production are not well understood. A 2-year field


Effects of nitrogen fertilizer on CH4 emission from rice fields: multi-site field observations
There is an ongoing discussion of the possible effects of nitrogen (N) application on methane (CH4) emission from rice fields. However, the Intergovernmental Panel on Climate Change (IPCC)
Factors affecting methane emission from rice fields
Stimulation by ammonium-based fertilizers of methane oxidation in soil around rice roots
It is shown here that the activity and growth of such bacteria in the root zone of rice plants are stimulated after fertilization, and the bacteria responsible for this effect are identified using a combination of radioactive fingerprinting and molecular biology techniques.
Methane and nitrous oxide emissions from rice paddy fields as affected by nitrogen fertilisers and water management
Methane and N2O emissions affected by nitrogen fertilisers were measured simultaneously in rice paddy fields under intermittent irrigation in 1994. Ammonium sulphate and urea were applied at rates of
Nitrogen as a regulatory factor of methane oxidation in soils and sediments.
Methane Emission from Irrigated and Intensively Managed Rice Fields in Central Luzon (Philippines)
Methane (CH4) emissions were measured with an automated system in Central Luzon, the major rice producing area of the Philippines. Emission records covered nine consecutive seasons from 1994 to 1998
Factors affecting methane production under rice
To understand why atmospheric methane is increasing worldwide, accurate estimates are needed of the global input from rice fields. We report greenhouse and laboratory studies over three growing
Effects of inorganic fertilizers and micronutrients on methane production from wetland rice (Oryza sativa L.)
We compared the effects of adding different forms of nitrogenous fertilizers on the production of CH4 in soil and on CH4 emission from rice plants, Urea and diammonium phosphate gave the highest
