Weathering intensity and trace elements (Ni, Sr, Zn, and Cr) distribution in Vertisols developed on basalt in a semiarid environment: agronomic implications

Frontiers in Soil Science
Chemical weathering, a major geomorphic process, controls soil formation and evolution at the Earth’s surface and is strongly influenced by prevailing environmental conditions.

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

, 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 ...
