abstract:
Three methods for the determination of water storage in 1 m deep peat-moorsh (MtIIbc) soil from Kuwasy, located in the Biebrza River Valley, were compared. The empirical equations for determination of water storage using measurements of groundwater level changes (method 1) and measurements of vertical changes of soil surface elevation (method 2) were used. Soil water storage in 1 m soil layer was also determined from direct field measurements of soil water content using TDR (method 3). The results of soil water storage obtained using method 1 were generally higher than the values determined using TDR (method 3), and the values of water storage calculated using method 2 showed slightly lower values in comparison with method 3. The values of water storage determined using direct field measurements of water content were characterised by the highest variability in comparison with the other two considered methods.
