Our goals are to clarify the biological and chemical processes affecting the relationship between soil water and nutrients and plant growth. Our focus is on investigation of the dynamics of water, nutrients and carbon in forest ecosystems and the interaction between nutrients and water and plants with the aim of evaluating the effect of anthropogenic and natural impacts on forest ecosystems.
