This study aimed to investigate the effects of cultivation practices on soil organic carbon sequestration associated with the distribution and stability of soil aggregates in tropical crop fields. The study analyzed soils collected from two long-term experimental sites with different fertilizer applications during the past 46 years. For cassava cul...

The default emission factor (EF) of 1.00% for direct nitrous oxide (N2O) emissions, as recommended by the Intergovernmental Panel on Climate Change (IPCC), is often applied in countries that lack region-specific N2O EFs, such as Thailand. However, this approach introduces significant uncertainty due to the spatial variability and complex dynamics g...

Alternate wetting and drying (AWD) water management is being promoted to replace continuous flooding (CF) water regime in rice cultivation for agricultural countries, including Thailand, to achieve the net zero greenhouse gas (GHG) emissions and cope with drought. However, its adoption in different areas yielding variable results that requires the...

Biochar application to agricultural crop fields could mitigates the emission of greenhouse gases, especially methane (CH4). However, the mitigation mechanisms are not fully understood. This study aimed to investigate the mechanistic effects of biochar on CH4 production and oxidation in incubated rice paddy soils collected from multiple sites in Tha...

Biochar has been recommended as a soil amendment to improve soil fertility and mitigate methane (CH4) emissions from rice cultivation. Its effects, however, vary depending on soil type, biochar characteristics, and application rate. This study was aimed to evaluate the potential of mangrove biochar on CH4 mitigation, soil properties, and the produc...

Application of biochar to the soil has been reported as one of the mitigation technologies of CH 4 emission from rice cultivation due to its unique characteristics of high porosity and surface area. The application of small particle size of biochar is rich in surface area that may enhance the mitigation potential. Rice cultivation and soil incubati...

Biochar amendment is generally recognized as an effective mitigation option of methane (CH4) emissions from rice cultivation. Although its mitigation mechanisms are not well understood, the potential relevance of surface area and porosity of biochar has been discussed. This study aimed to evaluate the application of different biochar particle sizes...

Biochar application and alternate wetting and drying (AWD) are emerging as promising technologies recommended for reducing CH4 emissions and water consumption in rice cultivation. In this study, we hypothesized that both technologies could be practiced in combination and this could further reduce CH4 emissions and water consumption when compared to...

Paddy fields are considered as one of the most important sources of anthropogenic methane (CH4) and nitrous oxide (N2O) emissions. While several technical options have been proposed to reduce these emissions, gaps in data and information based on application of these options in the field are a key barrier to scaling-up. To address these gaps, we co...

Alternate wetting and drying (AWD) system is a water management practice of rice cultivation that has been recommended and promoted to replace continuous flooding (CF). AWD could reduce greenhouse gas (GHG) emissions and save water use without compromising rice yields. However, its effects depend on how water level is effectively controlled. This s...

Alternate wet and dry (AWD) system is an interesting water management system that has been widely promoted to replace continuous flooding (CF) system as an effective water saving technique for rice cultivation. This study was conducted in wet season of 2015 and dry season of 2016 in Ratchaburi Province, Thailand, with a randomised block design to e...

Alternate wetting and drying (AWD) is a water-saving irrigation technique in a paddy field that can reduce the emission of methane, a potent greenhouse gas (GHG). It is being adopted to Asian countries, but different results are reported in literatures on methane, nitrous oxide emission, and rice productivity under AWD. Therefore, the local feasibi...

The experimental field was carried out to investigate the effects of a co-application of biochar and compost on methane (CH4) and nitrous oxide (N2O) emission, crop yield, and water consumption in two cultivation system including conventional and alternative wet and dry (AWD) systems using rice (Oryza sativa L.) cultivar of Pathumthani 1. Emissions...
