Basalt – Finely Ground Volcanic Rock

$7.00$32.50

Apply Volcanic Basalt Rock Dust because it is an excellent source of iron and other essential plant nutrients (including stem-strengthening silica). These are essential to plant health and vigor.  Additionally, recent research shows this amendment can capture atmospheric carbon dioxide, which should help combatting global warming and climate change!

Benefits of amending your soil with basalt rock dust include:

  • Good source of iron.
  • Contributes to the strengthening of cell walls.
  • Increases root growth and plant yields.
  • Carbon capture: Researchers are finding that when pulverized rock is applied to agricultural fields, the soil pulls far more carbon from the air and crop yields increase. More studies are underway, but some scientists say this method shows significant benefits for farmers and the climate, (Susan Cosier, 2021, https://e360.yale.edu/features/how-adding-rock-dust-to-soil-can-help-get-carbon-into-the-ground).
