- Abstract
The covering of potash tailings piles aims at minimising the rain induced brine formation. At the Zielitz site a new covering technique – the infiltration barrier system (IHS) – was developed. By adding insoluble compounds to the top layer of the tailings the water storage capacity and therefore the evaporation rate is improved. During field trials the growth of various photosynthetic active microorganisms and even small plants could be observed. These biological soil crusts can improve the evaporation rates at the surface, contribute to their stability and in the long term lead to soil formation, which finally facilitates settlement by higher plants.
