Applying the classic method of evaluation of soils „Romanian system of soil evaluation” the anthropic soils from mining quarries (sterile dumps) are considered to have almost the same productive potential with a natural soil as well as the evaluation marks. The goal of the present paper is to identify and adjust these indicators of the romanian system of evaluation in such manner the terrains affected by surface mining to be correctly evaluated. The researches carried out for the first time in our country in the domain of evaluating the entriatrosoils from sterile dumps have taken in account the changing and adjusting three of the romanian system of soil evaluation, namely soil texture under the form of textural variation, the humus reserve calculated on the basis of C/N ratio and the edafic volume determined on the basis of impenetrable formations for the root system of plants that were called „nodules” in such manner to reflect the reality of the production capacity of these anthropic soils from the mining basin of Oltenia. In this manner, the quality classes were as follows: class II with an evaluation mark of 63 points for the spolic entiatrosoil; class III with an evaluation mark of 43 points for the spolic entiantrosoil in conditions of homogenous texture and modified edafic volume; class IV with an evaluation mark of 36 points for the spolic entiantrosoil in conditions of heterogenous texture; Class V with an evaluation mark of 24 points. The improving of the evaluation system of soils with changes brought by the present paper for sterile dumps of 19,140 ha is important for: - elaborating pedological studies of class quality when the land is given back to the former owners in order to express the reality of the production capacity; - establishing the proper zones for cropping different crops for capitalisation of the land; - correct expression of the quality of natural and anthropic soils resulted from mining activity.
