Deficiencies of plant available water in soil catena of undulating ground moraine

Summary. The study presents the results of research on the deficiencies of water content in soil toposequence. The objective was to determine water deficiencies in soil in relation to the available soil water holding capacity (AWHC) and the soil location in a relief. The research results indicate a wide diversity of AWHC in the toposequence (catena), which is related to the complex movement, and distribution of precipitation water in the particular elements of the slope. The crop water deficiency and the depth of soil drying up are strongly determined by the location of the soil in the relief. During periods of vegetation the strongest and the deepest drying up is observed in the Aquic Glossudalfs of the ground moraine elevations in which the soil water dynamics is mainly determined by precipitation water. The drying up is weaker in the Typic Endoaquolls and weakest in the Cumulic Endoaquolls of the footslope, which display permanent capillary rise and lateral inflow.

Key words: water deficiencies, soil matric potential, toposequence, temporal variability
