I haven't been following this thread, but has anyone pointed out that clay is an aluminum compound? The alumina (Al2O3) used as as abrasive is very hard, inert, and not likely to be available to crop uptake. If you want to avoid aluminum in your diet, watch out for baking powder and self-rising flour. Both are commonly loaded witn SOLUBLE aluminum. Though, as has been pointed out, no aluminum connection is confirmed to alzheimers.

Been there, done that...the granite dust from tombstone cutting works well as a soil amendment...now here's possible downside:
The material used to polish blast and shine granite tombstones is aluminum, I believe aluminum oxide. The aluminum they buy in boxes, and they buy it every year. My way of thinking, that can only mean that the aluminum is ending up mixed with the granite dust. Can anyone prove this?
Can anyone prove that the aluminum constitutes a hazard applied to crops? Aluminum is implicated as a symptom of alzheimer's building up in the brain tissues of those with the disease...is it a cause of the disease or merely a symptom? Remember aluminum is everywhere in the soil.
I belive I first read about the free granite dust from something Lee Reich wrote...
Donna, thanks huge for your calculations on the Zinc, what a huge help!!! And may I ask, why apply Boron? I know pears have a considerable Boron content in the fruit.
