<i>F</i> values and significance level for the significant main effects from ANOVA of the tap root depth (D) and number of first-order roots (RNO), for which there were significant sediment effects, separately for each harvest time interval.

Superscripted numbers (1 and 2) indicate the error terms used in model, as follows 1 Plot (Treatment) with 15 d.f. 2 Plot (Treatment) × Sediment with 15 d.f. * p ≤ 0.05. ** p < 0.01. *** p ≤ 0.001. F values and significance level for the significant main effects from ANOVA of the tap root depth (D) and number of first-order roots (RNO), for which there were significant sediment effects, separately for each harvest time interval.
