Usage of birch logging residues for Scots pine seedlings growing

Established that the efficiency of forest residues in the form of woody vegetation during the growth of Scots pine seedlings with closed root system essentially depends on the volume content of this type of forest residues in the initial mixture for the preparation of the substrate. Composts made of wood wastes were studied. One-year-old Scotch pine (Pinus sylvestris L.) seedlings with the closed root system grew up on studied composts. Plants were grown in a glasshouse. Experiments have shown that the studied composts are suitable for cultivation of coniferous plants seedlings with the closed root system. The doze of entering studied composts can reach the third part from total amount of a substratum. Use of substrate from waste will allow to reduce considerably consumption of not renewing or slowly renewing resources to what peat concerns and to improve ecological conditions in region
