Fig. 3

Grey area on left y-axis represents mean daily new root production (cm cm−2 day−1) in mixed-vegetation plots in 2014, separated by soil depth. The date of peak root production was June 2 in 2014 and the average total root production from May 17 to September 5 2014 was 2.1 ± 0.2 cm cm−2 (±SE). The black line on the right y-axis is the estimated soil temperature for each depth. Error bars indicate ±1 SE. All treatments are combined (N = 24). Top row represent roots 1 to 10 cm below soil organic layer, second row represents roots 11–20 cm below soil organic layer, and bottom row represents roots 21–30 cm below soil organic layer. Figure is adapted from Radville et al. [55]
