Fig. 1. Mean gravimetric moisture content of the rototilled, disked, and control soils in the main experiment. The soils were tilled at 0 h. The time of irrigation (222 h) is indicated by the vertical dashed line. For reference, 110 g H₂O kg^-1 is equivalent to -50 kPa. The error bars are the standard error of the mean (n = 3).
