The Eliska Mine waste coal heap burned intensely in the 1960s and 1980s, and even now, on the surface of the heap, active vents still occur from which warm air (temperature 25–35 °C) and water vapor escape. In the neighborhood of active vents, the

Earthworms are important drivers for the formation of soil structure and play a key role in soil organic matter (SOM) dynamics. Our previous long-term (126 weeks) laboratory experiment showed that carbon (C) loss declined through time in soil when li

To understand why excrements of soil macrofauna often decompose more slowly than leaf litter, we fed Bibio marci larvae the litter of tree species differing in litter quality ( Alnus glutinosa , Salix caprea , and Quercus robur ) and then measured re

Incompletely combusted biomass ash containing unburned carbon is very often complemented by polycyclic aromatic hydrocarbons (PAHs). The straw ash containing PAHs, marked as hazardous waste, has been used as a filler in metakaolin-based geopolymers w
