The aim of the work was the determination of productivity index (PI) of soil in the area of exploitation activity of the Mine-Energetic Plant “Janina” in Libiąż using the Zhenqi Hu et al. [1992] method. Studies were carried out in mining subsidence basin in the Żarki village near Libiąż where two soil pits were realised and material for laboratory investigations was taken. Soil properties determined in laboratory used the Zhenqi Hu et al. [1992] algorithm method and values of PI were calculated. Mean value of PI amounted 0.67, which classifies the investigated area as one of the conditions for poor agricultural production. Changes of primary soil properties caused by mining activity of the Mine-Energetic Plant “Janina” had the highest influence on the calculated PIs. The determined PIs show the necessity of undertaking reclamation works for restoring primary properties of soil
