Evaluation of Cocomposted Coal Fly Ash on Dynamics of Microbial Populations and Heavy Metal Uptake

摘要: Vicia faba, in a pot experiment with sandy and clayey soils under greenhouse conditions, was checked for growth response to different amendments coal alkaline fly ash or cocomposted mixed lignocellulosic residues. Soil microbial populations, pH electrical conductivity as well heavy metal uptake by plants were monitored. At rates of five ten percent (on dry matter basis) both soils, neither alone nor exerted any negative effect. Plant biomass production not influenced either soil. Alkaline did promote when applied the soils. However, generally increased bacterial actinomycetes counts Fungi affected ash. Due increase soil ash, plant metals depressed Heavy mobility cause change where high buffering capacity mitiga...
