What always seems odd to me about the remineralization people -- at least the
ones I've run into at conferences trying to sell rock dusts -- is they don't
seem to want to pay attention to what's already in the particular soil.

Different soils are lacking in different things. Those things may or may not
be present in suitable amounts in the rock dust from any particular quarry.
In addition, different soils are high in different things, sometimes to the
point of excess at which they interfere with specific plants' ability to take
up other nutrients (a problem which may occur at different points with
different plants.) Those things also may or may not be present in significant
amounts in the rock dust from any particular quarry. But the recommendations
always seem to be, "It doesn't matter what's there to start with! Apply more
of our rock dust!" Isn't there a risk of getting soils further out of
balance, rather than further into balance? Lawrence's specific ground may
benefit from the minerals coming out of those specific quarries: but that
doesn't mean that all fields will be benefited by applying rock dusts from
any quarry/quarries willing to sell them.

And how much of the planet do we want to dig up in order to apply it to other
portions of the planet?
