RELATIONSHIP BETWEEN NORWAY SPRUCE STATUS AND SOIL WATER BASE CATIONS/ALUMINIUM RATIOS IN THE CZECH REPUBLIC

Popis výsledku v původním jazyce

The molar ratios of Ca/Al or (Ca+Mg+K)/Al in the soil solution have been widely used as a criterion for risk of tree damage due to acidification.Intensity and quality of the crown and branch structure transformation is a very sensitive indicator of long-term tree damage, and the subsequent regenerative processes. Soil water chemistry and crown structure transformation of Norway spruce was observed at 17 forest plots within the Czech Republic with following resultes:Total defoliation showed only low relationship with respect to soil chemistry. All remaining parameters, expressing degradation processes in the crown showed high correlation with soil water (Ca+Mg+K)/Al ratio in organic horizons. Surprisingly, no relationships were found for mineral horizons. Generally, considerably higher correlations between (Ca+Mg+K)/Al ratio in soil water and parameters of crown status compare to Ca/Al ratio were found.
