Went to lunch with a friend, a professor of horticulture. The main take-away is...data, data, data. Hard data on so-called 'natural' soil amendments and their outcomes is really lacking in the crunchy/hippie/re-mineralize movement's contributions to horticulture.
So why isn't this data out there? Or if it is, why isn't it more readily available to academic and industry experts? Here's what I found out on the intarwebs:
Rock Dust
Soil re-mineralization is all about putting back into the soil what has been removed unnaturally (by agricultural means). The idea is that, when plants grow in soils dense with trace minerals
Azomite is a rock dust product that comes from an ancient volcanic eruption in Utah. It contains over 70 trace minerals that are hard to come by in soils that have been used for human purposes over long periods of time. Amongst the list of minerals are (). Conveniently, their website has a list of application specifications, studies, and information. Very transparent, very modern, and very established (even a Wikipedia article).
