- •
We examined soil N and P cycling processes in forests in the northeastern US.
- •
Soil processes varied widely across forest stands but did not differ by stand age.
- •
Phosphatase activity and resin-available P increased with net N mineralization potential.
- •
Phosphatase activity did not contribute to broad patterns of P availability.
- •
Availability of N may limit soil phosphatase activity across these ecosystems.
