Abstract: Biomass nutrient loss and retention were studied at nutrient-poor forest site dominated by Scots pine where two methods of logging residues handling after clear-cutting were compared. The experiment was conducted on nutrient-poor pine-oak forest site on deep sandy-gravel unconsolidated sediments at the altitude of 255 m. There were three treatments established such as (i) control - no harvesting, (ii) whole-tree harvesting with ca. 10% of the slash retained unintentionally on site as processing residues and (iii) stem-only harvesting when small-diameter wood and slash were left on site. The third treatment was found to retain much larger amounts of nutrients in logging residues representing 16% of total above-ground dry mass which accounted for 58% of N, 32% of P, 56% of K, 22% of Ca and 28% of Mg left on site.
