The research was conducted on the external spoil heap of the ‘Piaseczno’ Sulphur Mine (southern Poland). This paper is aimed to compare the selected properties of macrostructure and density of wood of Scots pine trees planted onto the external spoil heap of the mine, in the scope of forest reclamation, depending on the soil substrate and employed reclamation treatments. The annual rings of pine trees on the Quaternary sands and Tertiary Krakowieckie clays (S&C) were significantly wider than those of the individuals on the Quaternary loose sands (S) and Quaternary sands and Tertiary clays after an intense initial fertilization (F). However, the share of latewood zone and density of wood of the pine trees growing on the substrate F were significantly greater in comparison to those of substrates S and S&C.
