Název v původním jazyce

The response of microbial activities on organic and inorganic treatments in a long-term heavy metal contaminated soil

Popis výsledku v původním jazyce

A pot experiment with a long-term heavy metal contaminated arable soil taken from the vicinity of the lead smelter was performed in a greenhouse. The lead smelter is situated near the city Příbram located about 60 km SW from Prague (Czech Republic). Non-contaminated arable soil taken from the same area was used as the control. The effects of zeolite, CaO and lucerne powder on microbial activities and heavy metal availability in the contaminated soil were studied in a pot experiment with triticale plants. The microbial biomass, dehydrogenase and arylsulphatase activities in the studied soils were determined after the plant harvest. The content of microbial biomass was higher in the contaminated soil than in the non-contaminated control. This result suggests that the microbial communities in long-term contaminated soils can be tolerant to heavy metal effects. Compared to control soils fertilized only with NPK, all kinds of treatments increased the microbial biomass in both studied soils.
