A Technosol in the FAO World Reference Base for Soil Resources FAO World Reference Base for Soil Resources is a new type of soil that combines soils whose properties and pedogenesis are dominated by their technical origin. They contain either a significant amount of artefacts (something in the soil recognizably made or extracted from the earth by humans), some sort of geotechnical liner, or are sealed by technic hard rock (hard material created by humans, having properties unlike natural rock).
