Albrecht's ideas of balancing Ca and Mg so that they occupy 80% of
cation exchange sites
This is important and worth learning about, but not from solomon. Readt
Albrecht directly. There are plenty of resources on this subject on the
web which can easily be found with Google. TPSL is knowledgeable about
Albrecht and would be an excellent lab to do your soil and plant tissue
testing. See their Ask The Plant program for more about that.
