Root length, diameter and density, density of extramatrical mycelia and root tips in the two soil horizons (upper horizon: 0–6 cm depth, deeper horizon: 6–16 cm depth, n = 5). Different letters indicate significant differences between treatments for the same harvest period. Different numbers indicate significant differences between harvest periods for the same treatment (P < 0.05). Values in italics for the deeper horizon indicate significant differences from the upper horizon.
