Figure 3. Porewater elemental concentrations in root- and bulk-zones across main-ratoon cropping season.

Caption

(a), (b) Boxplots compare porewater concentrations (μg L−1) of trace elements in root zone and bulk soil compartments between warmed (+5.65 °C on seasonal average), and control plots during (a) the main crop stage, and (b) the ratoon crop stage. Each point represents an individual sample; boxes indicate the median and interquartile range, with whiskers extending to 1.5× the IQR. Asterisks and 'ns' indicate not significant between control and +5.65 °C treatments by two-sided Mann–Whitney U test at p = 0.05 level.
