Site remediation of acid damaged soils using sprayed biosolids and lime : a case study of the area near the Trail lead zinc smelter in Trail BC Mattes, Al; Pommer, Matt; Duncan, William F. A. (William Frederick Alexander)


Research was completed on the use of two types of recycled waste products from the pulp and paper industry – composted biosolids and waste lime product – for use as a slurried sprayable soil amendment protocol. The material is first mixed as a slurry then seeds are added and the material sprayed using a commercial hydro seeder. Results from four treatments are reported providing details of seed germination, biomass produced and changes in soil pH profile. A separate study examined the use of this application on steep sandy slopes and initial results from this are reported as well.
