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?
“that if he meant total aluminum he is full of crap”
And there is no indication in the video this “IS” what he meant. You Assumed this on your own and ran with it... As for grams there are two measurements. If you had read the PDF link I shared it explains this.
“Exchangeable Al, ppm” and “Exchangeable Al, meq/100 g”. Milliequivalent per “100 Grams”.
