    Abstract : Popular Abstract in Swedish Under de senaste decennierna har det blivit allt mer uppenbart att det på grund av luftföroreningar skett en försurning av skogsjordarna i södra Sverige. Kalkning har föreslagits som en åtgärd för att motverka ytterligare försurning och bibehålla produktiviteten hos skogarna i de värst drabbade områdena. READ MORE

    Abstract : The thesis concerns the behavior of root and ectomycorrhizal (ECM) exudates. In particular, the dynamics of soluble low molecular weight (LMW) organic compounds such as organic acids (LMWOAs), amino acids, monosaccharides, and dissolved organic carbon (DOC) have been studied.
