摘要: The purpose of this paper was to characterise soil structure from the point view its aeration properties and verify applicability some methods for determination different related aeration. studies were performed on 15 representative samples Austria, Czech Republic, Hungary, Poland Slovakia. presents results measurements such as oxygen diffusion rate (ODR), redox potential (Eh), relative gas coefficient (D/D o ), air permeability (k), air-filled porosity (Eg) activity dehydrogenase catalase. All parameters D/D , ODR, k correlated with water content, porosity, bulk density particle density. In most cases indicators themselves also intercorrelated. both studied enzymes parameters. Threshold values physical conditions providing satisfactory status in particular profiles determined.
