The soil condition of spoil banks after agricultural reclamation in the North Bohemian Brown Coal Basin was evaluated in the pedologically oldest Anthroposols that were formed by direct and indirect reclamation of spoil bank substrates. We evaluated pelitic Anthroposols formed of grey Miocene clays, humic Anthroposols (overlaying of spoil banks with topsoil layer up to 0.3 m in thickness) and deep-humic Anthroposols (overlaying of spoil banks with topsoil layer more than 0.3 m in thickness) including the combined soil profiles when the spoil bank was overlaid with bentonites or loess loams before the final application of topsoil onto the surface. Deep-humic Anthroposol is considered as the highest-quality method of reclamation for agricultural purposes when the spoil bank surface is overlaid with topsoil layer up to 0.5 m in total thickness and where up to ca. 80% of output is reached in comparison with the best natural soils in the evaluated region. After the preparatory agrocycle is finished, the pedo-ecological evaluation of formed Anthroposols is done that is aimed at their classification in the system of agricultural land resources evaluation (evaluation of soil units ESU). In the North Bohemian Brown Coal Basin they are classified most frequently as Chernozems, scarcely as Rendzinas and Cambisols.
