VESELOVSKÝ, Filip: Evaluation of chemistry of spruce ecosystem soil solution at TMP Železnô and Lomnistá valley. [Diploma thesis]. – Technical university of Zvolene. Faculty of Forestry; Department of Natural Environment. – Supervisor: Ing. Marián Homolák, PhD.. Level of professional qualifications: Inžinier. An engineer, 2019. 54 part.The work is focused on chemical analysis of soil solution on permanently monitoring areas of two spruce ecosystems in the Low Tatras. Familiarization with sampling issues and its more detailed research in the laboratory. The data of laboratory measurements are used to produce graphs describing the content of chemical substances in the surveyed area from 2010 to 2018. The chemical composition indicates the proportion of necessary chemical elements for their health status as well as chemical elements of the air pollution load. On the basis of graphical data, we know better the response of forest ecosystems to changing climatic conditions and the subsequent evaluation of future development forecasts that we can influence for the benefit of forest ecosystems.
