Fig. 4From: Topography modulates effects of nitrogen deposition on microbial resource limitation in a nitrogen-saturated subtropical forestEffects of two-year N addition on the disoveled organic carbon (DOC), total disoveled nitrogen (TDN), available phosphorus (AVP), nitrification rate, and leaching rate of nitrate (NO3−). Error bars denote the standard error (n = 3). Different letters indicate significant difference (P < 0.05) between treatmentsBack to article page
