Abstract in another language
The influence of the distance to the stem on the chemical properties of soil and soil solution wereinvestigated in a mature European beech (Fagus silvatica L.) and a Norway spruce (Picea abies Karst.)stand by comparing areas close to stems with reference areas between stems. Under beech, significantchanges of soil chemistry close to the stem were observed. Distance from the stem influenced theexchangeable K, Mg, Ca and AI, as well as soil pH. Ca/A1- and Mg/Al-ratios of the soil solutionshowed higher values at the base of the stem. A significant increase of K and NO3-N concentrations ofthe soil solution close to the stem was found. No significant differences of soil analyses from referencesites and the base of the stem were detectable in case of spruce. Only the soil solution chemistry of thespruce site showed distinct spatial patterns. A significant increase of Ca, K and NH 4 concentrations wasdetermined next to the stem, while the concentrations of NO 3 were considerably decreased. Thesefindings suggest that the spatial heterogeneity of soil and soil solution chemistry related to stem distanceshould be taken into account when establishing element budgets and when evaluating the nutrientresources and the risk of acid toxicity to tree roots.
