↵zExplanations of model effects: W = water loss per day in a 6.4 m2 (69.1 ft2) planting pit (L/day, positive values); A = constant; B = block; P = period; T = treatment; L = length of period (days); RL = 1/L; S = soil water saturation level at the beginning of the periods (%); D = dummy variable (value 0 or 1) describing whether an irrigation was carried out or not on the day before the time domain reflectometry assessment at the beginning of the period; I = average daily stem basal area increment (mm2/day).
↵yEstimate is average of five blocks.
