METHOD OF SUSTAINING PLANT GROWTH IN HAZARDOUS SUBSTRATES, LIMITING THE MOBILITY OF SUBSURFACE CONTAMINANTS, AND BENEFICIATION OF NORMAL SOILS

摘要

A method of sustaining plant growth in toxic substrates polluted with heavymetal elements, characterizedin that it comprises amendment and remediation of the toxic substrates with abio-organic-zeoliticmixture. Vegetation, such as hyperaccumulator plants or native plants andgrasses for in situ remediation,will now grow, and the mobility of the subsurface contaminants will beinhibited. The method can alsobe used as a fertilizer and for beneficiation of normal, uncontaminated soils.
