The contribution of natural sorbents to the improvement of the properties of contaminated technosols evaluated by the development of vegetation cover

Kviatková, Tatiana, 1990- The contribution of natural sorbents to the improvement of the properties of contaminated technosols evaluated by the development of vegetation cover / Tatiana Kviatková, Roman Alberty ... [et al.]. -- Mining spoil heaps, as a remnant of extensive mining activity in many parts of the world, are considered as a serious contaminated site especially due to the high content of potentially toxic elements (PTEs) and acidic soil pH which also inhibits the development of vegetation cover. The aim of our paper was to experimentally test the effectiveness of natural sorbents (biochar, bentonite, organo-zeolitic substrate 1- 20 wt%, chicken manure) on pH technosol taken from two abandoned mining localities Cu mine waste dump Maximilian (Slovakia) and Fe Cu sulphide mine waste dump Libiola (Italy) and their impact to the support of grass mixture growth. We evaluated the height of plants, the weight of fresh aerial biomass and dry matter. Testing of the effectiveness of individual sorbents was performed by a pot experiment. The results showed that all tested sorbents statistically significantly (P < 0.001) increase the pH from technosols initially strong to ultra-acid (Maximilian heap pH 5.17; Li
