Impact of earthworms on trace element solubility in contaminated mine soils amended with green waste compost.
The common practice of remediating metal contaminated mine soils with compost can reduce metal mobility and promote revegetation, but the effect of introduced or colonising earthworms on metal solubility is largely unknown. We amended soils from an As/Cu (1150 mg As kg(-1) and 362 mg Cu kg(-1)) and Pb/Zn mine (4550 mg Pb kg(-1) and 908 mg Zn kg(-1)) with 0, 5, 10, 15 and 20% compost and then in...
متن کاملQuality of trace element contaminated soils amended with compost under fast growing tree Paulownia fortunei plantation.
The use of fast growing trees could be an alternative in trace element contaminated soils to stabilize these elements and improve soil quality. In this study we investigate the effect of Paulownia fortunei growth on trace element contaminated soils amended with two organic composts under semi-field conditions for a period of 18 months. The experiment was carried out in containers filled with tr...
متن کاملPhytoavailability of cadmium in long-term biosolids-amended soils.
Agronomic use of biosolids has raised concern that plant availability of biosolids-Cd will increase with time after cessation of biosolids application. It has been demonstrated that chemical extractability of Cd is persistently decreased in biosolids-amended soils. This study was conducted to determine if Cd phytoavailability in long-term biosolids-amended soils was also persistently decreased....
متن کاملHumic acid formation in artificial soils amended with compost at different stages of organic matter evolution.
A composting process was conducted under optimal conditions for 150 d, obtaining three biomasses at different levels of maturity: raw material (RM), fresh compost obtained after 11 d of composting (FC), and evolved compost (EC) obtained after 150 d of composting. During the composting process, HAs were extracted and fully characterized by mass balance, DRIFT, and 1H and 13C-nuclear magnetic res...

16 The common practice of remediating metal contaminated mine soils with compost can reduce 17 metal mobility and promote re-vegetation, but the effect of introduced or colonising 18 earthworms on metal solubility is largely unknown. We amended soils from an As/Cu (1150 19 mgAs kg and 362 mgCu kg) and Pb/Zn mine (4550 mgPb kg and 908 mgZn kg) with 0, 20 5, 10, 15 and 20 % compost and then intro...
