Fig. 1

The proportion of maximum seasonal root (standing crop) and shoot (NDVI) growth for mixed-vegetation plots in 2013 and 2014. Black lines with circular points indicate the mean proportion of maximum root growth, and gray lines with square points represent the mean proportion of maximum shoot growth. All treatments are combined (N = 24). Error bars indicate ±1 SE. The minimum and maximum root standing crops were 0.1 and 5.4 cm cm⁻² in 2013 and 0.09 and 4.4 cm cm⁻² in 2014. The minimum and maximum NDVIs were 0.07 and 0.88 in 2013 and 0.16 and 0.84 in 2014
