Can we measure soil salinity change?

By Gary Hutchinson, on April 14th, 2011

Unambiguous measurement of soil salinity can only be done on samples in the laboratory.

Typically the chloride (Cl-) concentration on a dry weight basis is taken to be representative. However, sampling is destructive and the chloride content varies both spatially and with time. So, only with a large number of samples taken systematically under . . . → Read More: Can we measure soil salinity change?
