Figure 2

Moss δ15N of individual FAAs in NanChang city. The vertical lines represent standard deviations. Moss δ15NTFAA and δ15NTN were showd in box plot. The box encloses 50% of the data, the whiskers 90% of the data, the solid lines is the median, the dashed line is the mean, solid circles are outliers. The δ15N ranges of the potential N sources are also included in the figure. The date of NHx δ15N values from excretory wastes is cited from Freyer59; Heaton60 and Moore61. NHx δ15N values from agricultural source is referenced from Xiao et al.58. The δ15N value of NOx is cited from Freyer59 and Saurer et al.67.
