Yeah - that’s mg/L or parts per million - they are the same thing.
That’s not “parts per gram” which literally doesn’t mean anything.
And, again to the point, that ONLY measures *bioavailable* aluminum for soil quality - which I have commented on repeatedly so far.
The ONLY way *bioavailable* aluminum goes up that high is if the soil pH went WAY down.
A REAL farmer who isn’t lying to you adds lime to his farm.
But, once again, as I have stated repeatedly, the symptom of high *bioavailable* aluminum is CHLOROSIS - which is bleaching of the plant. Not one bleaches plant in his video.
And what about him lying to you about his mature sunflowers?
Why are you defending these lies?
