streszczenie
This paper presents the results of the investigations of water-air relations in peat, sand and their mixture. It was stated that the addition of sand into peat radically changes its water-air characteristics, i.e., causes a considerable decrease of water amount bound in the mixture with different potentials and at the same time the increase of the soil air content. The analysis of ODR and Eh values lets us state that the addition up to 60% of sand into peat does not cause a significant improvement of the conditions of oxygen availability for plant roots.
