Srovnání střednědobé změny půdních vlastností mezi vybranými lesními porosty ve vegetačních stupních v Předních horách Moravskoslezských Beskyd
Matějčková, Michaela
This bachelor thesis deals with the issue of changing soil properties between forest stands in vegetation stages on a medium-term scale and their impact, significance and use in forestry practice. It is based on research that was carried out at the same locations before that time and on the data collected at that time (year 2010). Sixteen soil probes were excavated in artificial and natural stands and in four vegetation stages, samples were taken and then selected analyses were carried out in the laboratory, with the assumption of significant changes. These were, with two exceptions, very minor, which may be a positive aspect for the further development of the examined forest stands or for the inclusion of analyses in the restoration of “OPRL”, “LHP” or “LHO”. The mentioned differences in properties were especially in the B horizons of natural stands, namely for pH/KCl, where the value was significantly lower compared to the original state in the 4th vegetation stage, which indicates soil acidification. In the second case, it was a matter of differences between vegetation stages, again most markedly in vegetation stage 4, when the amount of total nitrogen increased significantly, which can be perceived in connection with a decrease in pH and could be justified by the manifestation of human influence, which is logically more intense in the lower vegetation stages compared to higher mountain positions.
