Volcanic Mineral Rock Dust
| |
Composition:
The mineral composition of a particular basaltic rock, calcium,
magnesium, and potassium silicates,supplies a range of
macro- and micronutrients that support plant growth.
|
  |
Replenishes the mineral content of highly weathered soils. |
|
Increases the cation status of soils. |
|
Reduces the acidity and phosphorus-fixing capacity of most soils. |
|
A tested soil amendment for use by organic farmers. |
|
Volcanic rock dust - a soil conditioner |
Results to date show that Mineral Rock Dust:
| |
|
|
rejuvenates mineral and chemical properties of highly weathered soils, |
|
increases negative charge in the soil, |
|
improves the cation exchange capacity of the soil, |
|
reduces soil acidity, |
|
reduces phosphorus fixation capacity of soils, |
|
enhances plant growth in difficult, highly weathered soils. |
