Abstract

Uncertainties concerning the fate in soil of potential contaminants in spent foundry sand (SFS), thus limiting their use in manufactured topsoils. A column experiment investigated plant growth, leaching and uptake of nutrients, trace elements, and organics from blends of SFSs and composts. Ryegrass growth was excellent with no toxicities. Very small effects on uptake and leaching of trace elements and organics were associated more strongly with compost than SFS. Large differences in macronutrient leaching were attributed to the type of compost. SFSs with low trace element content can be safely utilized for manufactured soil production however composts used could leach large quantities of nutrients. spent foundry sand, compost, manufactured soil.
