Fig. 1. An example of the linear relationship of soil solute storage verus time, at early time, for an application rate of 3.3 cm h^-1 and TDR probe (0.2 m) at position 1.5 m during: (a) continuous solute application on soil surface (step input) and (b) flushing experiment. The first 14 points (t = 0 to 1 h) were used in both regressions.
