ABSTRACT

A numerical solution of the salt diffusion equation for nonstirred
bathing solution is presented Theoretical calculations of the salt diffusion
from a slab into a nonstirred bathing solution showed that there is no effect
of nonstirred bathing solution on the rate of diffusion if the ratio of macro
and microprobe volumes (β) is less than unity. Since under field conditions
the value of β for aggregated soils is much less than one. Therefore it
is suggested that the analytical solution of the diffusion equation for wellstirred
bathing solution can be used under field condition where bathing solution is
nonstirred.
