The purpose of this paper is to characterise the aeration properties of the profile situated at Tisice. The paper comprises results of measurements of different soil aeration properties such as: oxygen diffusion rate (ODR), air-filled porosity (Eg), relative gas diffusion coefficient (D/Do), air permeability (k), and redox potential (Eh) as well as dehydrogenase and catalase activity. Undisturbed soil cores (from a depth of 5, 20 and 40 cm) were tested after equilibration on kaolin tension plates of soil water tensions 0 (capillary saturation - pF0), 63 (pF 1.8), 159 (pF 2.2) and 500 hPa (pF 2.7). Significant correlations between the parameters tested were found.
