The purpose of the research was to assess the possibility to compensate for the volume and its 10−year increase lost on future crop and trainer trees removed from the strip−roads by the increased growth of trees at their edge. The assessment comprised the estimation of the compensation period length and its percentage value 10 years after cutting the strip−roads. The analysis also comprised 5−year−long...
Artykuł prezentuje ocenę skuteczności modeli predykcyjnych, tj. Hołdy, Gajdki i Stosa, Prusak oraz Poznański, z wykorzystaniem zbilansowanej próby badawczej w postaci sprawozdań finansowych. Materiał badawczy składał się wyłącznie z informacji finansowych jednostek gospodarczych skupionych w sektorze leśno-drzewnym. Okres analizy obejmował lata 2003-2012. Podstawową metodą wykorzystaną w badaniu była...
W badaniach podjęto próbę ustalenia wpływu metod przygotowania gleby oraz sposobów utylizacji pozostałości zrębowych na kształtowanie się wielkości biomasy części nadziemnej sadzonek 3-letniej uprawy sosnowej, pochodzącej z odnowienia sztucznego. Przeprowadzone analizy statystyczne wyników dowiodły, że istnieje silny wpływ metod przygotowania gleby na wielkość biomasy. W przypadku sposobów utylizacji...
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...
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...
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,...
