abstract
Observed climatic changes connected with an increase of temperature and a depression of ground water level motivated this joint investigation of Central Europe soils.
The purpose of this paper is to characterize the aeration status of two sites representing typical regions for the agricultural production of Lower Austria (Wieselburg and Fuchsenbigl) on the basis of results obtained in the frame of the multilateral Austrian-Czech-Hungarian-Polish-Slovak project on 'Assessment of Structure in Agricultural Soils' sponsored by the Austrian Ministry of Science and Research.
The paper comprises results of measurements of different soil aeration properties such as: oxygen diffusion rate (ODR), redox potential (Eh), relative gas diffusion coefficient (D\D0), air permeability (k) and activity of soil dehydrogenase. Undisturbed soil cores were tested in the range of soil moisture tension from 0 hPa (pF 0) to 500 hPa (pF 2.7).Statistical analysis of relationships between tested parameters were performed.
