The impact of root systems and their exudates in different tree species on soil properties and microorganisms in a temperate forest ecosystem.

Background: The species composition of tree stands plays an important role in shaping the properties of forest soils. The aim of our research was to determine the influence on soil properties of the root systems of six species of trees which form forest stands in the temperate climatic zone. The research covered areas including six tree species - Scots pine (Pinus sylvestris L.
