| Abstract/Contents: | "High levels of heavy metals and soluble salts often limit the use of waste composts as components of container media for the production of ornamental plants. This study was undertaken to determine whether leaching is a solution to minimizing heavy metal and soluble salt problems. After sequential metal extractions and initial readings of soluble salts, three basic waste composts: 1) yard trimmings (YT); 2) YT with biosolid (BS); and 3) municipal solid waste (MSW) with BS separately and each in a volumetric combination with sphagnum peat and pine bark formulating three additional media, were placed in columns and leached with distilled water at a rate of 1.5 mL per minute for five days. Heavy metals in leachates were measured and metal species in leached substrates were determined. Leached substrates were then used for seed germination, rooting of foliage plant cuttings and production of foliage plants. Results showed that soluble salts were greatly reduced by leaching; heavy metals in water soluble, exchangeable and complexed forms were leachable. The rate of seed germination, capacity of rooting and growth of foliage plants in leached media were comparable to those of the control medium. This study demonstrated that leaching can reduce metal concentrations and soluble salts in waste composts." |
