The potential of biosolids and flyash mixtures for soil remediation for revegetation of degraded land.

经过清理或采矿的土地的重新植被往往因表土质量差或缺乏表土而受到限制。通过将两种废物产品，生物固体和粉煤灰混合起来，对这些土地进行补救可能是可能的。该项目的目的是通过调查在有无土壤矿物质和肥料和石膏等土壤改良剂的情况下，生物固体和飞灰材料的各种混合物中的营养水平和污染物的归宿，确定这种土地补救方法的有用性。

Revegetation of land that has been subjected to land clearing or mining is often limited by the poor quality or lack of topsoil. It may prove possible to remediate these areas of land by incorporating a mixture of two waste products, biosolids and flyash. The aim in this project is to determine the usefulness of this method of land remediation by investigating the nutrient levels and fate of contaminants in various mixtures of biosolids and flyash materials, in the absence and presence of soil minerals, and soil ameliorants such as fertilizers and gypsum.
