bathing solution is presented Theoretical calculations of the salt diffusion
from a slab into a non-stirred bathing solution showed that there is no effect
of non-stirred 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 well-stirred
bathing solution can be used under field condition where bathing solution is
non-stirred.]]>Biggar, J.W. and D.R. Nielsen,19671967pp: 254-274pp: 254-274Crank, J.,19752nd Edn.,Pages: 414Pages: 414Coats, K.H. and B.D. Smith,196447384Deans, H.A. and U.
