A schematic diagram on shoot sampling strategies. In spring experiment: shoot samples for core-spot (black-shaded area) were collected within 0.275 m × 0.360 m directly above the ingrowth-cores. Samples from around-spot (grey-shaded area) were collected around the core-spot (0.361–0.720 m). Shoot samples from remote-spot (white-shaded area) were collected > 5 m away from the core-spots. In both experiments: shoots were sampled twice (week 4 and week 8). At week 4, young and old leaves were collected separately, whereas the entire biomass was collected at week 8
