abstract
The spatial characteristics of the field water capacity (FWC) of Polish soils have been presented. It was found that their values range from 3.9 to 45.5 %, vol. in relation to soil units and are mostly differentiated by the soil granulometric distribution. Variability of the value of field water capacity in in- dividual regions can be seen in the well delineated belt of the central uplands, foothills and mountain areas; it divides Poland into two structural zones for which the threshold FWC value in the surface layer and subsurface is 25 and 30% in the subsoil.
