Accelerated weathering of biosolid-amended copper mine tailings.
Application of municipal biosolids to mine tailings can enhance revegetation success, but may cause adverse environmental impacts, such as increased leaching of NO3- and metals to ground water. Kinetic weathering cells were used to simulate geochemical weathering to determine the effects of biosolid amendment on (i) pH of leachate and tailings, (ii) leaching of NO3- and SO4(2-), (iii) leaching ...
متن کاملBacterial populations within copper mine tailings: long-term effects of amendment with Class A biosolids.
AIM This study evaluates the effect of surface application of dried Class A biosolids on microbial populations within copper mine tailings. METHODS AND RESULTS Mine tailing sites were established at ASARCO Mission Mine close to Sahuarita Arizona. Site 1 (December 1998) was amended with 248 tons ha(-1) of Class A biosolids. Sites 2 (December 2000) and 3 (April 2006) were amended with 371 and 2...
متن کاملGermination and Early Growth of Brassica juncea in Copper Mine Tailings Amended with Technosol and Compost
Mine tailings represent a serious threat to the environment and human health; thus their restoration has become a major concern. In this study, the interactions between Brassica juncea and different mine soil treatments were evaluated in order to understand their effect on germination and early growth. Three soil treatments containing 25% and 50% of technosol and 30% of compost were prepared. G...
متن کاملNative Plant Production in Potting Media Amended with Anaerobic Digested Cattle Biosolids
Anaerobically digested cattle biosolids are a by-product of cattle waste processing for pollution control and biogas production, yet this material has potential as an economical component of potting mixes used for sustainable nursery container production. As an animal waste, this material could have valuable fertilizer properties that could reduce the amount of supplemental fertilizer applied t...
