those that follow the L.G.C. University  extension  PH. program,    the co-op  PH,  program.  the soil testing lab. fertility guidelines, PH program do and will always grow the majority of the average yields, year in and year out.

guys like Kip  Cullers  and others. 

are very much ( aware, )  and very (  knowledgeable  )  about the Soil C.E.C. and  the role the Soil Cations  Play in  ( Super Crop Production. )

They, and most good vegetable Farmers.  also know that their method of crop production, fertility levels is totally   NOT Politically Correct.

therefor they discuss the issue very Little. If at all.
