Název v původním jazyce

Microbial activities and heavy metal availability following the treatment of long heavy metal contaminated soils with humates and lucerne

Popis výsledku v původním jazyce

The effects of leonardites, solid and liquid potassium humates on microbial characteristics, K2SO4-extractable carbon, available heavy metal contents and pH were studied in incubation experiments using long-term contaminated arable and grassland soils from the vicinity of the Pribram lead smelter. The addition of humates increased soil microbial biomasses, K2SO4-extractable carbon contents and pH in the arable soil. An increase of microbial biomass C in a grassland soil over the control soil after addition of humates was observed even after two month of incubation. The concentrations of easily available metal decreased in variants treated with humates. An increase of EDTA-extractable metals was obtained during the first 10 days of incubation in the control soil and in variants treated with humates. The leonardite treatment sharply decreased soil pH and the microbial activities in soils and it increased available metal fractions extracted with NH4NO3. The subsequent incubation of preced
