From: Multi-omics reveals nitrogen dynamics associated with soil microbial blooms during snowmelt
Soil extractable N pools were quantified from September 2016 to September 2017 at East River, CO (September, June and July n = 12 at each soil depth; March n = 6 at each soil depth; May n = 9 at each soil depth). a–c, Stacked bars depicting the magnitude of each soil N species relative to each other across timepoints and depths. d–i, Time-series of each N species highlighting differences across timepoints. Coloured lines represent weighted means smoothed by loess fitting of the temporal trend at each depth of sampling. Shading represents 95% confidence interval (CI) around the loess fit. The effects of month of sampling, depth and their interaction were tested using a two-factor ANOVA, P values are shown in d–i. The snowmelt period (March to May) is depicted on the x-axis in c–i.
