Response of Soil C and N, Dissolved Organic C and N, and Inorganic N to Short-Term Experimental Warming in an Alpine Meadow on the Tibetan Plateau

Figure 1

Effects of experimental warming on soil organic C (SOC), total N (TN), dissolved organic C (DOC), dissolved organic N (DON), the ratio of DOC to DON (DOC/DON), soil inorganic N (N_min), ammonium N (NH₄⁺-N), nitrate N (NO₃⁻-N), and the ratio of NH₄⁺-N to NO₃⁻-N(NH₄⁺-N/NO₃⁻-N) in the three alpine meadow sites located at elevation 4313 m, 4513 m, and 4693 m, respectively (mean ± SE, 𝑛=4). *indicates 𝑃<0.05, while no asterisk indicates not significant.
