The performed investigations concerned the effect of the application of different methods of management of cutting residues and ways of soil preparation on height changes of a five-year old pine cultivation. Both methods of residue management and ways of soil preparation exert a significant influence on the height of cultivation. Out of the applied five methods of management of clear-cutting residues, the following two turned out most favourable: a) the method which involved chopping of the residues and mixing them with the surface soil layer and b) leaving intact felling residues on the soil surface. On the other hand, the best way of soil preparation was ploughing furrows by a double-furrow plough with a simultaneous softening of the furrows with a subsoiler.
