abstract:
The article base on research realised on post-wetland�s peat � moorsh soils, which represent peat ecosystems of low (soil Mt Iba) and high (Mt IIcc) transformed, used as high fertilised meadows. Authors discovered, that in conditions when capillary rising from saturated layer equals water looses for evaporation, the soil moisture in root layer has constant value, independent from evapotranspiration height. That constant value can be different as a result of groundwater table depth and soil type. Presented in paper relations had been used to estimation of optimal dehydration depth. This value is diversified in dependence of evapotranspiration height and soil type. The presented relations can be also used for irrigation management of dehydrated peat ecosystems, high and low transformed, in the aspect of their sustainable development. Material included in paper can be also used as a data for calibration of mathematical models which simulate capillary rise rate as a supply factor of evapotranspiration demands, for steady state flow conditions.
