Fig. 5. Salinity tests: (A and B) Tree 1 perlite shallow probe (#8, 200 mm) _perlite and _perlite and (C and E) Trees 1 and 2 (70 mm) averaged _stem and _stem during a salinizing-leaching cycle (maximal _drainage = 5.2 dS m^–1, DOY 136–157), and (D and F) during a second salinizing-leaching cycle (maximal _drainage = 13.2 dS m^–1, DOY 180–212). Boxed values indicate timing and _irrigation.
