Effects of liming on the microbial biomass and its activities in soil long-term contaminated by toxic elements

Popis výsledku v původním jazyce

The effects of liming by CaO and CaCO3 on soil microbial characteristics were studied during laboratory incubation of long-term contaminated arable and grassland soils from the vicinity of lead smelter near to Pribram (Czech Republic). The CaO treatmentshowed significant negative effects on soil microbial biomass C and its respiratory activity in both studied soils, despite the fact that the microbial biomass C in the grassland soil increased sharply during the first day of incubation. The metabolic quotient (qCO2) in soils amended by CaO showed from the second day of incubation greater values than the control indicating a possible stress of soil microbial pool. The vulnerability of organic matter to CaO could be indicated by the availability of K2SO4-extractable carbon which increased sharply particularly at the beginning the experiment. The amendment of soils by CaCO3 increased moderately the soil microbial biomass. The respiratory activity and qCO2 increased sharply during first da
