Estimate of available nutrients in forest soil after bark beetle outbreak of stands after salvage logging and of stands left without intervention in the Šumava National park
DRÁBKOVÁ, Marie
The aim of this study is to estimate and compare the amount of available nutrients in forest soil of stands where the salvage logging took place after the dieback of the forest caused by bark beetle outbreak and of stands left without any intervention in protected areas in Šumava National Park. The study also focus on the influence of the vegetation cover and decaying wood on the soil chemistry, especially on the cationt exchange capacity, base cationts and aluminium contents.
