Soil gas diffusion measurements: effect of root mucilage analogue from chia seeds on soil gas diffusivity

Title: Soil gas diffusion measurements: effect of root mucilage analogue from chia seeds on soil gas diffusivity

Description: The effect of a mucilage analogue from chia seeds without intrinsic respiratory activity on oxygen diffusion was measured at different water contents during wetting-drying cycles in a diffusion chamber experiment. Artificial soils of various particle size distributions were mixed with various amounts of the mucilage analogue. Additionally, environmental scanning electron microscopy (ESEM) was used to visualize mucilage bridges in the dry soil samples.
