Constructed soils (also called fabricated … Constructed soils (also called fabricated soils) are mixtures of organic and mineral material derived from a number of sources, including repurposed organic waste, that are designed to approximate natural soils and provide a growing medium for plants. Constructed soils are commonly used in the reclamation of degraded land where natural topsoil is either not present or has been contaminated. Examples of these sites include mines, landfills, and other industrial or urban areas. Constructed soils are classified as Technosols, and often form the upper layer, or layers, in a Technosol above a geomembrane or other barrier capping waste material. Use of constructed soils in restoring sites is preferable to importing topsoil from other locations. Topsoil harvesting means a second location will be degraded, and collection and transport expenses will generally be higher than using local materials to create a new soil. Soil that was removed and stockpiled (e.g. during the operation of a mine), can become part of a constructed soil once a site is being reclaimed. The goal in designing a constructed soil is to replicate the physical, chemical, and biological functions of natural soils. The target soil properties depend on the site location and final land use. Constructed soils are intended to be as low-maintenance as possible, meaning they will be a stable and functional system over time that does not need additional inputs once biogeochemical cycling is established. Where applicable, constructed soils must meet regulatory requirements dictating the acceptable thresholds of certain soil characteristics. Pathogens, harmful trace elements, salinity, and pH must be at values that are not harmful to human or environmental health. Specific values for the balance of soil nutrients, including proportion of organic matter, carbon to nitrogen ratio, and total nitrogen, may also be required to ensure prolonged soil functioning.ired to ensure prolonged soil functioning.
