Abstract:
The ability to uniquely resolve these solute variations is attributed in part to specific characteristics of the Santa Cruz site, e. g., the development of a prominent argillic horizon which spatially isolates the lithogenic and biogenic processes and to the strong season control on hydrology and plant growth. Although both processes occur in most soil environments, resolution comparable to that obtained in this study may be more difficult. The ongoing development and use of other parameters, including Sr, Ca, N and Si isotopes and Ge/Si ratios further our ability to distinguish between biogenic and lithogenic processes in such soils.
