Název v původním jazyce

Changes in cadmium mobility during composting and after soil application

Popis výsledku v původním jazyce

The effect of twelve weeks of composting on the mobility and bioavailability of cadmium in six composts containing sewage sludge, wood chips and grass was studied, along with the cadmium immobilization capacity of compost. Two different soils were used and Cd accumulation measured in above-ground oat biomass (Avena sativa L.). Increasing pH appears to be an important cause of the observed decreases in available cadmium through the composting process. A pot experiment was performed with two different amounts of compost (9.6 and 28.8 g per kg of soil) added into Fluvisol with total Cd 0.255 mg kg_1, and contaminated Cambisol with total Cd 6.16 mg kg_1. Decrease of extractable Cd (0.01 mol l_1 CaCl2) was found in both soils after compost application. Thehigher amount of compost immobilized an exchangeable portion of Cd (0.11 mol l_1 CH3COOH extractable) in contaminated Cambisol unlike in light Fluvisol. The addition of a low amount of compost decreased the content of Cd in associated abo
