Migration of gases in agricultural subsurface and emission across the soil-atmosphere interface is primarily diffusion-controlled and is explained by soil-gas diffusivity. Since experimental determination of soil-gas diffusivity demands expensive apparatus and time-consuming controlled laboratory measures, predictive models are commonly used to estimate diffusivity from easy-to-measure soil properties like soil total porosity and soil-air content.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-05-gas-diffusion-aggregated-soils.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Modeling gas diffusion in aggregated soils<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Agricultural soils contribute to 16% of total Greenhouse gas emissions, particularly nitrous oxide (N2O).
