摘要

On the basis of the studies presented and maps constructed on their basis, the following can be concluded: 1. potentially useful retention (PUR) of arable Polish soils ranged from 2.1 to 27.2% m~3 m~(-3), 2. most of the arable soils of Poland is characterised by values of potentially useful retention (PUR) between 12 and 18% m~3 m~(-3), 3. the highest differentiation of potentially useful retention (PUR) was observed in the subsoil, and the lowest in the surface layer of the arable Polish soils. The cartographic presentation of the values of potentially useful retention (PUR) divides Poland into two spatial structural units; the first, very differentiated unit, covers highland, foothills and the Karpaty and Sudety Mountains, is characterised by the predominance of the highest PUR values; the other, less varied, covers the Polish Lowlands and Lake Districts and is characterised by the predominance of the soils with medium PUR values.
