Using constructed soils for green infrastructure – challenges and limitations

Urban Farm DB summary

This review examines the use of Constructed Technosols (CTs), mixtures of organic and mineral waste, for green infrastructure (GI) in urban spaces. While CTs have high potential to provide multiple soil functions and contribute to urban greening, urban soils are often physically, chemically, or biologically unsuitable for GI features. The analysis suggests that the composition and structure of CTs should be adapted to available wastes and by-products, as well as future land use and environmental conditions, highlighting the need for careful design to overcome existing limitations.
