Researchers show how excavated soils from #constructionsites can be upgraded with #organicwaste for reuse in cities. By adjusting mixtures, soils can support #greenspaces or #groundwater protection: http://go.tum.de/306737

Recycling urban soils

Researchers at TUM have investigated so-called “constructed soils” and show that they increase fertility and the ability to bind pollutants.

As an #urban #forest in the outskirts of #Berlin with diverse ecosystems, #Grundwald forest boasts a high #biodiversity. Special is the #Teufelsberg area, a #debrispile from #WorldWarII and home to diverse dry forest-#meadow# habitats. However, according to G. Wessolek & A. Toland (2017), the chemical properties of these special #urbansoils have potent and negative impacts on their #ecosystems.

Want to gauge your #SoilHealth? Soil structure (and structural stability) is the foundation of high-functioning soils. We are working on a reboot of the Slakes app so you can get a proxy for aggregate stability in your kitchen. Beta testing the app with #UrbanSoils of #Bogotá. #Rstats package for multi-sample analysis coming soon. #suelo #SueloUrbano
