摘要：

Groundwater regime and mineralization process in moraine sandy loam and peat soils of the active sulphatic karst zone (karst processes develop in the Upper Devonian gypsum-dolomites) in Lithuania and the dependence of chemical compounds concentrations on water level fluctuations are reviewed. According to ion sum, groundwater mineralization in peat soil is 1.1-1.3 times higher than in loam soil. Based on this result, lower levels of groundwater predetermine a more intensive mineralization process. A stronger correlation was determined between groundwater levels and concentrations of chemical compounds (Ca2+, Mg2+, SO42- and HCO3-) enhancing groundwater mineralization. In mineral soil (sandy loam) nitrate (NO3)(-) concentration is highly influenced by changing stages of groundwater level as well as by nearby sinkholes.
