Impact of plant roots and soil organisms on soil micromorphology and hydraulic properties

Original language description

A soil micromorphological study was performed to demonstrate the impact of soil organisms on soil pore structure. Two examples are shown herre. First, the influence of earthworms, enchytraeids and moles on the pore structure of a Grayic Phaeozem is demonstrated by comparing two soil samples taken from the same depth of the soil profile that either were affected or not affected by these organisms. The detected image porosity of the organism-affected soil sample and soil microorganisms in a Haplic Luvisoland subsequently affected by clay coatings. Their presence was refelcted in the soil water retention curve, which displayed multiple S-shaped features as obtained from the water balance carried out for the multi-step outflow experiment. Thedual permeability models implemented in HYDRUS-1D was applied to obtain parameters chracterizing multimodal soil hydraulic properties using the numerical inversion of the multi-step outflow experiment.
