Abstract
Effects of northern red oak on the forest soils were studied at the locality on the territory of the University forests of the Czech University of Life Sciences, Prague. The red oak stand part was compared to a stand part composed of native broadleaves with the dominance of European beech in a 71-year-old stand at the altitude 400 m a.s.l. The site was characterized as acid oak-beech site with Luzula nemorosa. Samples were taken in autumn 2022 for horizons L+F1, F2+H (quantitatively), and Ah, B in 4 replications. Results confirmed slight acidification of the upper soil horizons, consisting of a soil reaction decrease, bases content and base saturation, and especially worsening of the nitrogen dynamics, i.e. increase of the C/N ratio. Northern red oak was documented as a mildly acidifying species in given site conditions and its relevance should be limited to degraded sites and as a species, planted in conditions where domestic species cannot thrive.
