| I am reading Neil Kinseys book and am not sure on one point. He says that if you add the Calcium and Magnesium % of base saturation together they should stay under 80%. I have several tests over 90. PH's are around 6.7. Besides Nitrogen I am not sure what I need to apply to get the base CA-MG% under 80%.
At what % do you start worrying about this?
If I applied gypsum wouldn't the sulphur and Calcium cancel each other out and not make this any worse? I am deficient in Sulphur so I think I can apply the Gypsum and not hurt anything.

Calcium-Magnesium base % over 80% from Kinsey
