<p>Methane (CH<sub>4</sub>) is a potent greenhouse gas contributing to climate change, with global warming potential of 24x CO<sub>2</sub> on 100-year time-frame. More importantly, the atmospheric methane concentration has been rising rapidly in last decade. Soils are as yet only known biological sink for methane, but uptake capacity agricultural soils substantially reduced when compared native soils. This may be due reduction soil organic matter and aggregate stability result management practices. In this study, we improved laser-diffraction analysis-based modelling stability. Using data from an extensive field show new relationships between stability, uptake, matter. The use amendments like compost increases content, which improves that enhances uptake. These results provide insights mitigation strategy.</p>
