Is rock dust the answer to renewing barren soils?

Two former schoolteachers in Britain have been saying so for 20 years. They've been growing "cabbages the size of footballs, onions bigger than coconuts and gooseberries as big as plums" in soils that were formerly barren. The rock dust is a byproduct of quarrying and is said to mimic what glaciation does to fertilize the land with needed minerals.
