The treatments were: (1) no thinning, (2) light thinning, and (3) heavy thinning. Prior to thinning, the stand averaged 15000 trees hal and 40.0 m2 ha·1 of basal area, with an average mean diameter of 5 cm. Thinning reduced stand basal areas to about 31.1 and 24.9 m2 ha-1 for the light and heavy thinning treatments, respectively. After 3­ years, diameter increment was the highest in heavily thinned stand and the lowest in unthinned stand. The increment in stand basal area was about 10, 1Band 27 % in the unthinned, lightly thinned, and heavily thinned stands, respectively. Fine root biomass significantly decreased with thinning and thinning had no significant effects on soil pH and soil organic matter content.eninfo:eu-repo/semantics/openAccessFagus orientalisThinningGrowthRoot biomassSoil propertiesArticle261919516114466
