A field experiment was conducted in 1996-1997 and it aimed at assessment of different methods of soil preparation in Scots pine natural regeneration originated following the shelterwood cutting system. The experiment was established in the Puszcza Solska Forest. Soil preparation was made with forest plough (LPz-75), disc harrow (BT), and disc plough (PTL-2). It turned out that in the first year the best results were observed in the forest plough (LPz-75) treatment with 11.8 N/m2 seedlings at the beginning of the vegetation season and 4.6 N/m2 at the end of thereof. The second year number of seedlings was maintained at a similar level, but seedlings from the disc harrow (BT) variant were higher and much more vital than those in other variants. According to the present experiment, variants with forest plough and disc harrow are to be recommended for practical use.
