Figure 2: Volumetric water contents of soil profiles (0–200 cm depth) close to silking (R2) and at physiological maturity (R6) of maize crops cultivated at three landscape positions (summit, shoulder-slope position, and foot-slope position) and three row spacings (0.38 m, 0.52 m, and 0.38 m in a 2 × 1 skip-row pattern) during 2007/08 (location 2; L2). Values are the mean ± standard error of three replicates. Dotted lines indicate volumetric water contents at lower limit, upper limit, and saturation determined in laboratory.
