No more conversions!

Who knew first principles of conversion could desert you! I used to rag the 2nd year engineering students I helped tutor at UJ about forgetting about converting between units and orders of magnitude. Now it's my turn to blush. I had to convert a concentration of base cations (mg/l) into a mass-based concentration (cmol/kg). This was not a trivial exercise. About 100 Google searches on concentrations and conversions and numerous Aardvark queries later, I finally got the solution put together. The results look realistic compared with another years set of results and they are an interesting contrast to the base cation concentrations of soils determined by another method. This is a good thing!

On with presenting this data in a meaningful way. Oh first the stats...
