Abstract:

The main goal of this doctoral thesis was evaluation of the effect of different tree species on the initial soil formation processes on post-mining sites. Study locations included four reclaimed spoil heaps in Sokolov brown coal mining basin in the Czech Republic. A comprehensive analysis of physical and chemical properties of soil formed under various (broadleaved and coniferous) woody species monocultures of the same age was performed. The obtained results have shown that broadleaved species such as black alder (Alnus glutinosa), beech (Fagus sylvatica), small-leaved linden (Tilia cordata), maples (Acer platanoides, Acer pseudoplatanus) and pear (Pyrus communis) have generally exhibited more favourable soil properties and soil formation potential (observed through the depths of formed diagnostic horizons) than the other broadleaves and coniferous species tested. However, the growth potential and resistance to climatic extremes of some, both native, and introduced conifers (Pinus sylvestris, Pinus nigra, Larix decidua, Pseudotsuga menziesii, Picea omorika) has shown that these species can be suitable afforestation species for post-mining sites in this region. The indisputable effect of time on initial soil forming processes was assessed through a chronoseqence of 3 differently aged forest reclamation sites, as well as through observation of chemical properties on Lítov spoil heap after 20 years.
