This paper presents the results of studies on the influence of soil preparation methods and ways of utilization of logging residues on belowground biomass of 3-year-old Scots pine saplings, after artificial regeneration. Statistically significant correlations were detected between root biomass and soil preparation methods, while there was no significant impact of logging residues management. Furthermore, interaction of methods of soil preparation and various ways of logging residues management also did not affect the belowground biomass of the plants. The greatest biomass was detected on the area where the soil was prepared by ploughing furrows with the LPz-75 plough. On plots where the soil was prepared by scarifying with rotary tiller, the lowest values of belowground biomass were observed.

The aim of this study was to determine the influence of soil preparation on height of 3-year-old Scots pine plantation. Three methods of cutting residues management and three methods of soil preparation were analysed. Height structure was determined and mean heights in specific variants were statistically analysed. Conducted analysis showed, that the influence of soil preparation method was much greater than cutting residues management. Statistically significant impact on tree height was found in case of scarifying and mixing of topsoil with rotary tiller, where greatest mean height was observed. Ploughing furrows with LPz-75 plough proved to be the most beneficial method of soil preparation. In this case the greatest heights of 3-year-old Scots pines were measured.

This paper presents the results of studies on the influence of clear-cut site management on survival rate of 3-year-old Scots pine saplings, conducted in the Forest District Bierzwnik in September 2011. Statistical analysis showed, that only the soil cultivation method significantly influences the survival rate on the studied Scots pine plantation. No statistically significant influence of cutting residues management or combined methods of residues management and various variants of soil cultivation was found.
