Graphical abstract of a scientific paper showing drawings of a helicopter fertilizing a forest, a harvester cutting down a tree and a tree stump next to a pine sapling with ectomycorrhizal fungi on its roots. In a 2 panel figure data on the organic layer carbon stock in fertilized and unfertilized forests is shown. In the left panel right after clearcutting, where there is a larger carbon stock in the previously fertilized clearcuts. In the right panel 4-13 years after clearcutting, when there is no longer a significant difference in soil organic layer carbon stocks.

New paper alert. We compared foliar fungal communities in native and introduced populations for a pine species (Spoiler alert: fewer pathogens in exotic populations). Shout out to an excellent international network of collaborators. 👇👇👇

Every expt is humbling—I learn how much I don’t know about forests. This latest expt was no exception. In response to 13 yrs of N addition, we measured fungal mass (dead/alive), chitin conc, root tannin conc, and potential genetic capacity of EcM fungi. No trt effects detected!

In their 2021 study, @j-karst.bsky.social et al found that 13 years of N addition in boreal aspen forests was linked with more "high biomass" ectomycorrhizas. Does that translate to more fungal necromass in the soil?...
