The challenge of restoring degraded landscapes or ecosystems and recultivating them in a way that maximizes the multifunctionality of the artificial soil depends on the extent of soil degradation and its causes. The process of land restoration is expensive, time-consuming and requires careful planning and collaboration between different stakeholders and sectors. In densely populated regions such as Central Europe, there are two major types of artificial soil ecosystems: restoration of landfills or mining pits and urban green infrastructure (e.g. urban tree sites, stormwater retention areas). To compensate for the increasing scarcity of arable land, soils with unfavorable properties must be improved and degraded land must be rehabilitated in order to fulfill soil functions and promote agricultural production.Engineered soils offer a solution for construction the top layer that allows the restored ecosystem to function. Such soils are made from excavated material and other mineral or organic waste and are composed to provide suitable conditions for plant growth and other ecosystem services provided by the soil.As the need for green spaces in urban areas is also increasing, e.g. to adapt and mitigate the urban heat island effect, soil is needed as a habitat for plants and engineered soil mixtures are required depending on the target location and purpose. Soil mixtures with suitable chemical, physical, biological and geotechnical properties (i.e. physical structure) are needed, w...
