Nitrogen deposition and soil phosphorus

Summary

Does long-term nitrogen deposition lead to increased microbial mining for phosphorus in organic and mineral soils, and what is the consequence for the soil carbon sink? This project use the long-term nitrogen addition experiment at Svartberget and ingrowth cores with needle litter, humus, and mineral soil with and without elevated phosphorus content. Substrates were collected in a phosphorus addition experiment in the Tönnersjöheden research forest in Halland.
