Abstract: Soil substitute capable of supporting plant growth is produced in quantities suitable for substitution on a large scale, such as in landscaping operations. Shredded treebark is intimately mixed with quarry stone particles and silica sand particles and are then composted while mixed with the quarry stone particles and sand particles. Composting is performed by laying out the mixture in windrows and aerating the shredded treebark by mechanically turning material in the windrows so that composting proceeds within the temperature range 42-60 degrees Celcius.
