Nonlinear response of soil respiration to increasing nitrogen additions in a Tibetan alpine steppe

Nonlinear response of soil respiration to increasing nitrogen additions in a Tibetan alpine steppe

Nitrogen (N) availability is a key regulator of carbon (C) cycling in terrestrial ecosystems. Anthropogenic N input, such as N deposition and fertilization, increases N availability in soil, which has important implications for an ecosystem’s C storage and loss. Soil respiration (Rs), which is the s...
