Rock Dust Can It Remineralize the Earth? Garden Myths

网页2018年3月12日  The rate at which rock dust dissolves and releases its nutrients depends on the type of rock, the type of soil, the pH of soil, climate, and the mineral balance in the soil (ie presence of other minerals). There is almost zero dissolution in alkaline soil, and a much higher rate in very acidic soil. Low mineral, tropical soils dissolve faster
