Influence of vegetation on phenolic acid contents in soil

The study described in this paper was undertaken in order to assess the impact of different woody plants on the dynamics of phenolic acids in soil. The influence of plant litter on the amount of phenolic compounds occurring in soils beneath several deciduous and coniferous tree species was examined in pot experiments. The contents of endogenous methanol soluble free and conjugated phenolic acids in Norway spruce, larch, rowan and two species of willow were determined. We focused on the dynamics of water-soluble and reversibly bound phenolic acid contents in the upper layers of soil substrates in pots after the cultivation of studied woody plants.
