abstract: The aim of the investigation carried out was to study some properties of arable soils of the Landscape Park "Podlaski Przełom Bugu" and to estimate the usefulness of these soils. The research proved the remarkable share of skeleton in most of the soils, and the occurrence of stones within the whole profile in some soils. As compared to brown soils, podzol soils showed stronger acidity. The latter, together with rusty soils, were richer in humus, compared to podzol soils and soils lessivés. Higher sum of basic cations and higher degree of base saturation were recorded in brown soils. Ca++ dominated among exchangeable cations, the proportions of Mg++ and K+ were also significant. A characteristic feature of soils of the area, not only of arable soils, was the occurrence of carbonates and alkaline reaction in the soils derived from loose sands. It refers mainly to rusty soils. The usefulness of arable soils of studied area was evaluated as average. Black earth and lessivés soils were the best among the profiles analysed. They were mainly in bonitation class II. The worst of all were podzol soils (VI bonitation class). The usefulness of the soils studied was considerably reduced by high content of skeleton with postglacial stones.
