AbstractThe aim of the study was to determine the effect of different management treatments of Norway spruce post−harvest logging residues on soil properties. The study compared the impact of residues chipping and arrangement into the stacks. The investigation was carried out in the Nowy Targ Forest District (southern Poland). 15 research plots were selected for the analysis (5 plots with wood chips, 5 with stacks and 5 control ones). In May 2018, on each research plot soil samples for laboratory analysis were collected from the surface horizon (0−10 cm depth). Basic properties (pH, carbon and nitrogen content, base cations content) and enzyme activity (dehydrogenase, urease and �−glucosidase) were determined. The obtained results confirm the influence of post− −harvest logging residues management on soil properties. The significant differences in soil carbon content between soils of different plots variants were noted. Soils of research plots with wood chips and stacks were characterized by higher content of carbon compared to the control research plots. At the same time soils with post−harvest logging residues had a higher biochemical activity expressed by enzymatic activity. The nutrients released from decaying post−harvest logging residues stimulated the microbiological activity of the soils.
