Fig. 1. Comparisons of runoff between reverse osmosis water (RO) and a 50:50 mix of RO water and tap water (RO/Tap) and between soil loss and sediment concentrations in the runoff waters. Regressions, except for sediment concentration, are significant; runoff differed significantly among the three irrigations (P 0.05). Dashes signify 1:1 lines.
