Bio-physical competition for pore space and the micro-environment in BSC covered Kalahari Sand soils: Modelling soil thermal, hydraulic and gas efflux behaviour
Soil pore and particle matrices both facilitate and constrain soil-atmosphere exchange of heat, moisture and gas. Further, in soils covered by Biological Soil Crusts (BSCs), soil structure differs in the BSC (<1cm) and near surface layers. Soil-atmosphere gas exchange occurs primarily by diffusion, moisture flow by capillarity and hydrostatic pressure, …
