Carbohydrates leaving plants contribute to the pool of dissolved organic carbon in soil, postulated as a very attractive carbon source for microbial growth. By reason of increasing concern of tropospheric ozone damage on forest trees, this study focused on European beech (Fagus sylvatica L.) and Norway spruce (Picea abies (L.) Karst.) as experimental plants, since these are common in forests of Western Europe. Using different 13C-labelling techniques, individual groups of organisms were identified to be involved in the utilization of exudates, indicating a microbial food web in the rhizosphere ...
