Max,

I think calcium and magnesium are critical in the soil but I have never 
seen soil tests express it that way. I thought the ideal 
calcium/magnesium would be a a percentage of base saturation (70%/12%). 
Having said that, however, when Richard got his numbers, I believe the 
results showed less calcium as a % than that, but "high". Is there 
something you know that I don't?

Thanks,

Jim
