ABSTRACT
In Scotland, no account of the ef‹cacy of adding mineral-rich dust, produced purely from crushing and screening mineral-rich rock to a ‹ne power and adding to compost, soil, and wormeries, would be complete without reference to SEER Rockdust and its co-founders, Cameron and Moira Thomson. This inimitable Scottish couple devoted their lives to demonstrating and developing a brand of powdered rock, which they called SEER® Rockdust® and I ‹rst visited them in November 2004.
