Using [delta] ph as a geochemical index of illite neoformation in saprolite [PDF]

open access: yes, 2008
Sal pH is routinely measured for agronomic purposes. When the difference between KCI pH and H2O pH, or ApH, yields positive values, it is used by soil scientists as a classification criterion for identifying anionic subgroups according to the Soil ...
