The dataset contains the results of analyses of physical and chemical properties, metapopulation of bacteria, and enzymatic activity in 40-year-old Technosols developing in an open-pit mining area under alfalfa (Medicago sativa L.) cultivation with the addition of grasses (Dactylis glomerata L.) at different levels of mineral fertilization under static field experiment conditions.
