Abstract: A numerical solution of solute transport from a single spherical aggregate when subject to different leaching techniques is presented in this paper. Theoretical calculations of leaching with different techniques showed that with rest periods (pure salt diffusion periods) equal to on periods (water application periods) water saving equal to 50% were possible with Intermittent Leaching (IL) when compared with Continuous Leaching (CL). However, water savings with IL increased rest periods such that during leaching by increased duration of rest periods to twice of the on periods water savings up to 66% were calculated. Calculations revealed that saturated IL was more water use efficient than that of drained (empty macropores) IL.
