Fig. 5. Comparisons of volumetric water content from DPHP sensors at 5 (A) and 15 cm (B) among MSL, PSL, MSNL, and Ambient soil, and at 25 cm (C) among MSL, PSL, and Ambient soil. Vertical dashed lines highlight irrigation date. Symbols (x) along abscissa of each graph indicate significant differences between MSL and Ambient soil (P < 0.05), diamond-x indicates significant differences between MSL and both Ambient soil and MSNL, and plus (+) indicates significant differences between both MSL and PSL and the Ambient soil on a given day (at 1800 h).
