Soils and substrates associated with denuded sites from construction, mining, energy development and other land disturbing activities are inherently lacking in organic matter, nutrients and biological activity essential to sustainable vegetative establishment. Ideally these sites would be covered with several inches (centimeters) of rich fertile topsoil to help develop a reasonable growing medium. However, there is simply not enough suitable or reasonably priced topsoil to ameliorate inhospitable conditions on every site.
