Fig. 6.

Above–below-ground time series from the mesocosm experiment. (A) The relative, 3 d smoothed segmented root surface area (sRSA), root length density (RLD), GCC (greenness of above-ground vegetation), and root mass, showing parallel development all scaled 0–1. (B) The 5 d slope of biomass-related values (i.e. rate of change) where at some periods GCC is increasing faster than sRSA and at others sRSA is increasing faster than GCC. Blue lines show watering events which are scaled in width relative to the volume of water applied.
