[Elektronische Daten] [Hooshang Majdi, Jan-Erik Nylund] We studied effects of nitrogen, other nutrients and water (liquid fertilization; LF) on fine root dynamics (production, mortality) and life span of mycorrhizal short roots in a Norway spruce stand, using minirhizotrons. Data were collected and analyzed during a two-year period at depths of 0-20 cm, 21-40 cm and 41-85 cm, six years after the start of treatment. Relative to control (C), root production was lower in LF plots at depth 0-20 cm. Root production increased significantly at depth 41-85 cm. Fine root mortality in LF plots was higher at all depths. Life span of mycorrhizal short roots in LF plots was significantly lower than C plots and at the end of the study no mycorrhizal short roots were alive. It is suggested that the water and nitrogen input lower longevity of mycorrhizal short roots and promote fine root production at deeper soil layers.
