Abstract [en]

Extramatrical mycelium (EMM) of mycorrhizal fungi have a fundamental role in carbon (C) cycling in forest ecosystems. This carbon is used for building extensive mycelial networks in the soil as well as for metabolic activity related to nutrient uptake. Here we discuss the factors that regulate the production and turnover of EMM and its role in soil C dynamics and nitrogen retention. C availability seems to be the key factor determining EMM production and possibly its standing biomass in forests but direct effects of mineral nutrient availability on the EMM can also be important. There is great uncertainty about the rate of turnover of EMM, and the increasing evidence that residues of EM fungi play a major role in the formation of stable N and C in soil organic matter highlights the need to include mycorrhizal effects in models of global soil C stores.
