Changes in Physical and Water Retention Properties of Technosols by Agricultural Reclamation with Wheat–Rapeseed Rotation in a Post-Mining Area of Central Poland

During opencast lignite mining, the natural landscape is damaged, along with soils, and new anthropogenic landforms are created which require reclamation. Usually, evaluation of effects reclamation (mostly forestry) concerned changes in chemical properties first years, mainly surface horizon. This study analyzed effect long-term agricultural (43 years) on physical water retention Technosols. The experiment involved cultivation winter wheat oilseed rape under 3 fertilization variants. After 43 an Ap horizon (Ap1 Ap2) developed fertilized Technosols, but was not clearly formed unfertilized minesoil. In Ap1, there improvement quality (S), bulk density (BD), particle (PD), structural stability index (SI), soil porosity (SP), air-filled (AFP), field capacity (FC) plant available (PAWC). Ap2, were comparable to those Technosols observed before Regardless fertilization, deterioration parent materials. general, have improved horizons, increasing above requirements does lead their further enhancement.
