  1. Note that Sample ID (SB and BF) refers to field samples, whereas ID numbers of the size fractions are those assigned by CSIRO, Earth Science and Resource Engineering, Kensington, Western Australia during separation and analysis and are the ones used in their internal database. Note also that the analysis of K is given as % K, and not %K2O (e.g. Clauer 2013)
