Gaia Green Basalt Rock Dust is an organic basalt rock dust soil amendment for re-mineralizing depleted soils and potting mixes. This mineral soil amendment is designed to bring natural minerals and trace elements back into the root zone, supporting steady garden performance with a simple, single-input approach.
Basalt is a mineral-rich, volcanic rock, and Gaia Green Basalt Rock Dust is noted as being high in magnesium, iron, calcium and silica. Those mineral highlights make it a practical fit when you want broad-spectrum mineral support without relying on a blended fertilizer. Because it’s a finely ground rock dust, it’s built for use in soil-building projects where improving the mineral profile of your growing media is the priority.
This product is also positioned for more than plant nutrition alone. Gaia Green describes a wide-range of trace elements that support both plant growth and soil biological activity, which matters when you’re aiming for a living, resilient soil that can cycle nutrients effectively over time. In that role, basalt rock dust works as a soil remineralizer that supports long-term fertility goals, helping keep the growing environment supplied with naturally occurring mineral inputs that plants need to thrive.
Gaia Green Basalt Rock Dust is derived from basalt, keeping the ingredient base straightforward. It’s intended for use on farms, home gardens, landscapes and turf, and it’s described as suitable for a full range of plant types. If you’re looking for a finely ground rock dust to re-mineralize depleted soils and potting mixes, and you want natural minerals and trace elements that support plant growth and soil biological activity, this basalt rock dust is a good fit for growers focused on soil-building and consistent root-zone mineral support.
| Calcium (Ca) | 1.7% |

| Total Magnesium (Mg) | 1.0% |
| Total Iron (Fe) | 5.5% |
| Total Manganese (Mn) | 0.08% |
Basalt mostly helps plants indirectly by improving the root-zone environment through better drainage, oxygen flow, and long-term soil stability, while only slowly contributing minerals as it weathers over time. It’s unique because its biggest benefits come from physical soil performance and consistency rather than quick nutrient release like fast-acting amendments.
Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.
Total iron (Fe) matters because iron supports chlorophyll development and plant energy systems, keeping new growth green and vigorous; it’s unique from many other nutrients because iron deficiency usually shows up first in young leaves even when older leaves stay green, since iron doesn’t easily move within the plant.
Total magnesium is important because magnesium powers chlorophyll and energy use, helping plants stay green, turn light into growth, and use other nutrients efficiently—and it’s unique because its problems often come from nutrient balance and uptake competition, not just a simple shortage.
Total manganese matters because it supports photosynthesis and enzyme activity that keep new growth green and vigorous, and it’s unique because “total” manganese measures what’s present but not necessarily what the plant can absorb—so pH and root conditions decide whether manganese helps or harms.
