Microbial biomass carbon concentrations (bar graphs) under drought, rainfed, and irrigated treatments at 0–5 (a,b), 5–15 (c,d) and 15–30 (e,f) cm depths during 2018 and 2019. Different letters represent statistical significance at p ≤ 0.05 at each time point. No letters mean no statistical significance. The secondary axis represents the hyphal length (line graph) in each treatment at each time point. The hyphal length was not determined for 15–30 cm depth (e,f) as microbial biomass carbon did not show significant differences between treatments. Asterisk represents statistical significance at p ≤ 0.05 at each time point. Error bars represent standard error (n = 3). Sampling in May represents baseline and in November represents post shelter removal. Vertical dashed line represents shelter establishment date and solid line represents shelter removal date.
