Abstrakt (anglicky)
   There is a concern that soil cidification by acidic deposition, along with the resulting depletion of the labile pool of nutrient cations (e.g. Ca, Mg) and enhanced leaching of Al from soil may contribute to forest dieback. 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 damages due to acidification. Intensity and quality of the crown and branch structure tranformation of secondary shoots in successive series is a very sensitive indicator of long-term tree damages, and the subsequent regenerative processes.
   Soil water chemistry and crown structure tranformation of Norway spruce were observed at 16 forest plots within the Czech Republic with the following results: parameters, expressing degradation processes in the crown (defoliation of primary structure), regeneration processes (percentage of secondary shoots) or synthetic stages of crown structure transformation showed high correlation with soil water (Ca+Mg+K)/Al ratio inorganic horizons. No relationship were found for mineral horizons. The correlations between soil water and crown status parameters were considerably stronger when using the (Ca+Mg+K)/Al ratio rather than Ca/Al ratio
