Effects of Calamagrostis epigejos, Chamaenerion palustre and Tussilago farfara on nutrient availability and microbial activity in the surface layer of spoil heaps after hard coal mining

“…Indeed, this element (in the exchangeable form) occurred in large quantities even in bare spoils. The content of organic C in the study spoil was similar to (Bens and Hüttl, 2014;Chmura et al, 2011), or higher than (Abakumov and Frouz, 2014) that recorded at different sites after coal mining. It was only slightly lower than the content of total C (organic C followed much the same pattern as total C), suggesting that almost all of the carbon contained in the spoil material was related to organic matter of recent, or geogenic, origin (Bens and Hüttl, 2014;Frouz and Nováková, 2005).…”

As non-vegetated spoils had relatively high amounts of organic C, this element must have been largely in the form of fossil organic compounds and/or organic matter of ancient shales (Abakumov and Frouz, 2014).…”
