The Impact

This study examined the interaction of tree species and soil development in litter and the 0-10 cm mineral topsoil layer in European beech, Norway spruce, and sessile oak forests. It also compared the main soil chemical, physical, and selected microbiological indicators as well as the microbial biomass, basal and substrate induced respiration, lipid phosphate content, phospholipid fatty acid profiles (PLFA), and respiratory quinones (RQ). With Norway spruce, soil pH, clay, and silt content were significantly lower, while exchangeable acidity was higher. This leads to a major loss of exchangeable cations of the upper soil layer resulting in lower base saturation. The microbial metabolic activity and microbial biomass of deciduous forest soils were significantly higher. The respiratory quotient (q) was highest in spruce, indicating disadvantageous circumstances for microbial activity. Our results demonstrate the importance of a complex study of physicochemical and biological soil parameters when investigating the impact of forest management on soil by, for example, providing data for the development of forest condition monitoring activities.

Correlations of increment indexes with average monthly temperatures and total monthly precipitation were studied on annual ring series of 455 trees of Norway spruce (Picea abies [L.] Karst.), sessile oak (Quercus petrea Liebl.) and European beech (Fagus sylvatica L.). Data on precipitation from the period 1901–2005 and on temperatures from the period 1931–2005 were used. Statistically significant dependences with correlation coefficients in the range of 0.2–0.5 were confirmed. All tree species react positively to precipitation mainly in June and July. An increase in precipitation by 1 mm when compared with the long-term average results in an increase in increment index of spruce almost by 0.13%. This index in oak and beech increases only by a half value of the value for spruce. Precipitation from the second half of the vegetation period of the previous year is also important. Higher temperatures during the vegetation period affect increment changes mostly negatively. With temperature increase by 1°C, when compared with the long-term average, the increment index of trees decreases by about 1–2%.
