Saprotrophic and mycorrhizal effects on decomposition at different rates of nitrogen deposition

Summary

This project utilised the Åheden long-term nitrogen addition experiment with five nitrogen addition rates and a trenching/tree root isolation treatment in a split plot design. We measured decomposition in needles and humus incubated in the soil and profiled the microbial communities using a combination of PLFA and fungal DNA sequencing.
