Short summary
PROFILE base cation weathering estimates using the directly measured XRPD mineralogy compared to different indirectly determined A2M mineralogies (regional versus site-specific) were overall similar. However, the underlying contribution from different minerals to the overall rates differed. Descriptions of the dissolution rate kinetics of the plagioclase mineral group as well as major K-bearing minerals (K feldspars and micas) should be improved for future soil and forest management studies.
