Aeration properties on the example of arenic chernozem (Tisice) [Czech Republic]

1998

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.
