DESCRIPTION:The rhizosphere is certainly the most relevant soil hotspot def
 ining the quality and quantity of our crops. Most of the biogeochemical an
 d physical differences between the rhizosphere and the surrounding soil ar
 e caused by the release of rhizodeposits into the soil. Rhizodeposits modi
 fy the activity and growth rates of heterotrophic soil microorganisms and 
 alter community structure in the vicinity of roots. This impacts 1) soil o
 rganic matter decomposition (rhizosphere priming effect) and 2) the C tran
 sfer through the decomposer system.\nThe first part of the presentation fo
 cuses on the effect of rhizodeposition on soil organic matter (SOM) turnov
 er. Root morphology (e.g. root hairs) alters exudation and\, hence\, micro
 bial-mediated processes in the soil. While barley with root hairs enhanced
  SOM decomposition (69% above unplanted soil)\, barley without root hairs 
 in comparison suppressed SOM decomposition by 28%. The present study sugge
 sts that rhizosphere priming effects are intimately linked to root morphol
 ogy.\nThe second part of the presentation concentrates on root-C transfer 
 through the food web of an arable soil. The complexity of soil food webs a
 nd the cryptic habitat hamper the analyses of pools\, fluxes and turnover 
 rates of C in organisms and the insight into their interactions. Our study
  showed that\, although the fungal C stock was less than half that of bact
 eria\, C transfer from fungi into higher trophic levels by far exceed that
  from bacterial C. This challenges previous views on the dominance of bact
 eria in root C dynamics and suggests saprotrophic fungi to function as maj
 or agents channelling recent photoassimilates into the soil food web.\n***
