The effects of litter position on carbon (C) release for experimental species during 12 months of litter decomposition in different plots. Values presented were means ± SE (n = 5). Different lowercases indicated significant difference at P < 0.05. Leymus tianschanicus from N9 plots (N9-L. T litter); Leymus tianschanicus from N0 plots (N0-L. T litter); Festuca ovina from N9 plots (N9-F. O litter); Festuca ovina from N0 plots (N0-F. O litter).
