Název v původním jazyce

The role of phosphorus, magnesium, and potassium availability in soil fungal exploration of mineral nutrient sources in Norway spruce forests

Popis výsledku v původním jazyce

Fungal growth and community composition was investigated in buried meshbags, amended with apatite, biotite or hornblende, in Norway spruce (Picea abies) forests of varying nutrient status in the Slavkov Forest Critical Zone observatory, Czech Republic. Norway spruce needles and soil collected from forests overlying serpentinite had low levels of potassium and phosphorus, those from granite had low levels of magnesium, while those from amphibolite had comparably high levels of these nutrients. Fungal colonization of meshbags was assayed by measuring ergosterol content and fungal community with 454 sequencing of the ITS region. In addition, fine root density was measured. Fungal biomass was increased by apatite amendment across all plots and particularly on the K- and P-deficient serpentinite plots, while hornblende and biotite had no effect on fungal biomass on any plots. Fungal community (total fungal and ectomycorrhizal) composition was strongly affected by sampling location and soil depth, while mineral amendments had no effect on community composition. Fine root biomass was significantly correlated with fungal biomass. Ectomycorrhizal communities may respond to increased host-tree phosphorus demand by increased colonization of phosphorus-containing minerals, but this does not appear to translate to a shift in ectomycorrhizal community composition. This growth response to does not appear to exist for potassium and magnesium limitation.
