Lesson 32 Mineral Cycling - Alaska Geobotany Center

Adding ground
glacial rocks to
remineralize soils
• John Hamaker, a farmer in Michigan,
started a movement to remineralize
the Earth by spreading glacial dust
over declining forests and croplands.
What started as a “fringe”
movement has gained scientific
support through large programs in
Europe to spray ground rock over
forests declining from acid rain.
