Short summary
Here, we measured soil EEA using a gradient of incubation temperatures in 78-year-old tree plantations. We established a new tree species–enzyme–C/N model to explain why exotic slash pine can grow faster, as it has longer residual soil N residence time than native pine specie. To our knowledge this is the first study to clearly show that when soils with different C contents are subject to warming, high C soil has more C losses but differences in residual C between them become larger and larger.
