Mitigation of Acid-Producing Soils

摘要

This project produced a method for stabilizing the pH of acid-producing soils in order that the soils could support the growth of vegetation needed to minimize erosion. Recipes for the modification of acid-producing soils have been successfully used by the National Minelands Reclamation Center and the Arkansas Power and Light Co. Those recipes rely on the ability of a fly ash/kiln dust to bind with the sulphur in the soils to thus minimize the production of Sulfuric acid. This project used a mixture of lime-stabilized sewage sludge as an amendment.
