rendzina - Opis:
- Chemical denudation plays a crucial role in affecting the water chemistry and the development of the relief, therefore the dissolution of carbonate rocks is the subject of numerous research. The aim of the study was to determine the effect of soil material derived from the organic (O) as well as humus (A) horizons of forest soils (common beech and Norway spruce stands) on the dissolution of rock. During one−year laboratory experiment standardized samples of dolomitic limestone placed in the soil material were washed with deionized water. The greatest loss of the sample rocks mass occurred in O material from Norway spruce stand (43.9‰ on average), while in other cases, the loss of rock samples mass was much lower and statistically non−significant. The total masses of calcium (Ca2+) leached from O material under beech and spruce stands were similar, however in the case of spruce most of Ca2+ derives from rock dissolution. Similarly, higher proportion of magnesium (Mg2+) leached from O material under Norway spruce derives from rock dissolution, although the total mass of Mg2+ leached is higher from O material under beech. The total mass of Ca2+ and Mg2+ leached from A material was similar or higher than from O material, however most of those ions derived from the soil material. The results indicate that the replacement of beech by Norway spruce can increase chemical denudation as well as Ca2+ and Mg2+ leaching, wherein Ca2+ leaching would be significantly greater than Mg2+.
