Another question: base saturation of elements are given in % - per cent of what? Is it the whole exchange points?
Further Solomon writes P (Phosphrous) should be equal to K (Potassium). What comes first P or K or do I raise my P to the amount of K - this would mean 506ppm P to the amount of 728ppm K?
I don't trust my own calculations and I really want to get it right!

If you can locate a source of that mineral, you will be able to bring the P and K into balance with a simple single application.
BTW, the ppm to kg/ ha i found in Solomon's worksheets he writes: 1 ppm = 2 pounds/acre = 2.24 kg/ha - do I get something wrong?
