In this contribution an accumulation capability of soil in the East Slovak Lowland has been quantified and economically evaluated relating to water retention; and using comparable parallel with water surface reservoirs. Accumulation capability investigating from soil profile thickness 0.0–0.1 m was determined from the porosity distribution (as its upper limit) and hygroscopic coefficient (as its lower limit). According to analysing of soils by particle grain size fractionation, concretely by content of the 1st particles category (less than 0.01 mm), six representative soil profiles, characterizing typical soil textural classes, were selected. For these soil profiles following hydro-physical parameters were analyzed total water capacity, point of decreased availability, wilting point, hygroscopic index. These parameters were used for calculation of accumulation capability of soils. Maximum retention water capacity, is defined as difference between porosity, or total water capacity, and hygroscopic index. It corresponds to active reserve and retention capacity of surface water reservoirs. This capacity calculated for deep soils of the East-Slovak Lowland reaches 2 860–4 207 cubic m per ha. For economic pricing of soil accumulation function available data about investment costs for maintenance of 1 cubic m water in Zemplínska šírava water basin were used. The actual price level was estimated on about 0.5 Euro. Using characteristic status of soil moisture and above mentioned price, the total price of agricultural land on the East Slovak Lowland relating to water accumulation capability is approximately 361, 811, 000 Euro, or circa 1, 727 Euro per 1 hectare.
