Fig. 5.

Moisture content in sand at different depth ranges in pots when the pots were irrigated initially with water equivalent to 8 mm, 16 mm or 24 mm of rainfall and subsequently not irrigated at all ([8+0], [16+0] and [24+0], respectively), or irrigated initially with water equivalent to 16 mm of rainfall and subsequently with water equivalent to 3 mm of rainfall at 1-d intervals ([16+3]). Moisture content in sand was measured 3 d (filled circles), 5 d (filled squares), 10 d (open circles), 15 d (open squares) or 25 d (open triangles) after the beginning of irrigation. Moisture contents 15 d and 25 d after irrigation for [8+0] and moisture content 3 d after the beginning of irrigation for [16+3] were not measured. Each point represents the mean of four replications; error bars indicating standard error are shown only where it was larger than the point size.
