Vliv půdních vlastností na genezi vegetačních typů spontánně regenerovaných a lesnicky rekultivovaných ploch ve vápencovém lomu Mokrá

The role of soil properties for the vegetation development during early spontaneous succession and forest reclamation was studied in a limestone quarry Mokrá (south of Moravia). Spontaneously regenerated areas were studied mainly with the aim to detect the soil environment features supporting the swards formation of expansive reed grass (Calamagrostis epigejos), which is able to arrest a succession process. Forestry reclaimed areas were study with the aim to compare soil properties of prosperous and decline sites. We examined water air regime, soil reaction (pH), soil texture, soil organic carbon content (SOC), total nitrogen content (Ntot) and content of available Ca, Mg, K and P. The multivariate statistical approach revealed the fact that soil texture, SOC, Ntot and water air regime were statistically significant for the spontaneously regenerated vegetation types. Reed grass preferred fine grained soils with higher SOC and Ntot content. Content of clay, sand and available K were statistically significant for decline and prosperous sampling sites. However any soil property could be called as a cause of prosperity or decline
