Hydraulic conductivity under various recultivated growth

Velka podkrusnohorska spoil heap in the Sokolovsko region is the largest heap in the Czech republic, which was created by transfering millions of tons of soil from opencast mining of brown coal. According to a large measuring (large land surveying) of physical and chemical properties on the reclaimed and unreclaimed heap soil were found many hydrological properties. Hydraulic conductivity was measured by Guelph permeameter, moisture was measured by Dielectrical indicator of moisture and last but not least soil carbonates Ca was measured by Janek`s carbonmeter. Water mode and percantual representation of carbonates is markedly influenced by the technology of sending and by the age of heaps of both types, differencies between bottom parts and top parts on unreclaimed soil are conclusive due to crevasses on the top parts. The other factor is the presence of reclaimed vegetation, which have an important role in the pedogenic process
