- Association Mycelial C:N declined with increasing N supply.
- Intervention effect Addition of N increased mycelial growth at the low-N end of the gradient.
- Association Uptake of added N and C by ECM mycelium was inversely related.
- Association The use of added N by ECM mycelium was high when ambient N was low.
- Association The use of added C by ECM mycelium was high when C from photosynthesis was low.
- Association ECM fungi appear to have a major role in soil N retention in nutrient-poor but less so in nutrient-rich boreal forests.
