“have a PhD in physical chemistry and maintain a small personal farm.”
Which is why you should not have made that mistake in the real math. I am a Geologist and understand elemental soils a bit myself. Whether it be mining or agriculture the elemental assessment content of soil or stone does not change. Right off the bat you should have known that 5% aluminum content of all soil does not equate to 5% as “Exchangeable” aluminum content. There is a huge difference between the two.
Which is why - in POST #2 - I differentiated between the two, and posted repeatedly that if he meant total aluminum he is full of crap and if he meant bioavailable aluminum he is a crappy farmer who hasn’t maintained soil pH.
Go look at the posts and tell me I made the mistake you claim.
Now - again to the point - if his *bioavailable* aluminum is killing his plants it’s through CHLOROSIS - which is bleaching of the plant, so it does because it can do photosynthesis. Not one bleached plant in his video.
So, geoengineer - worried about bioavailable aluminum - how did you make that mistake?
And if you’re a geologist, why did you say, “parts per gram is how it’s measured.” That is a MEANINGLESS unit and any geologist would know that. Calling your bluff.
