Odnowienie naturalne sosny (Pinus sylvestris L.) na siedliskach wilgotnych przy zastosowaniu różnych metod przygotowania gleby

The paper reports the performance of pine culture established from natural regeneration in the moist mixed coniferous (BMw), fresh mixed coniferous (BMśw) and moist mixed deciduous (LMw) forest habitats in Pszczyńskie Forests. The seedlings were measured in the successive growing seasons following culture establishment. The soil preparation variants included: full beds, ridge beds, and strips using FAO−FAR soil cutter. The parameters subject to analysis embraced planting density, height and quality of seedlings taking into consideration soil preparation methods. The density of seedlings established on full beds was found to be the best, while on ridge beds – it was the lowest. Seedlings growing on strips showed the best height increment and quality, while those growing on beds – the poorest. The parameter variability between individual sites under the experiment was high.
