View larger version (25K): [in a new window]   Fig. 1. Root distributions used in the simulations. The numbers in the key refer to the maximum depth of root penetration and the letters refer to whether the roots were predominantly shallow (s) or deep (d) within the depth of penetration.

View larger version (41K): [in a new window]   Fig. 2. The measured (Meas., solid symbol) and simulated (Sim., open symbol) salt distribution at the end of the growing season for irrigation water salinities (dS m-1) as specified by the numbers. The results are for irrigation intervals of (A) 3.5, (B) 7, (C) 14, and (D) 21 d.

View larger version (28K): [in a new window]   Fig. 3. The simulated salt distribution at the beginning (initial) and end of the growing season for four root distributions. The numbers in the key refer to the maximum depth of root penetration and the letters refer to whether the roots were predominantly shallow (s) or deep (d) within the depth of penetration. The irrigation water salinities were (A) 1.75 dS m-1 and (B) 9.5 dS m-1.
