Last post of the series dedicated to soils of post mining sites. What are the most commonly used techniques for soil restoration at post mining sites and how do they work? Soils are a valuable resource and their protection in the course of mining and storage is extremely important to avoid irreversible damage. Soil management and replacement with exogenous soil is also very expensive. That is why the first priority should be to conserve the existing soil in the best possible condition.
Soil is closely connected to ecosystem development. In fact, the natural composition of soils is a result of interaction of the mineral substrate with the soil biota: microscopic and macroscopic animals, plants and their physiological activities. Other basic factors, such as the local climate and topography, as well as past developments over long periods of time set the scene. More recent factors, such as technical recultivation measures have a major impact on the restoration and functioning of soils.
