Agricultural rock dust is a natural soil amendment made by finely crushing basalt rocks ,into a powder or grit.
It’s sometimes called rock powder, rock minerals, or mineral fines.
Here’s a breakdown:
Re-mineralization – It replenishes soils with essential trace minerals that may have been depleted through years of farming or erosion.
Microbial support – Soil microbes use these minerals to break down organic matter and make nutrients available to plants.
pH balancing – Certain rock dusts can help neutralize overly acidic soils.
Improved plant health – Over time, plants grown in re-mineralized soil may show better resistance to pests and disease.
Rock dust doesn’t feed plants directly in the way synthetic fertilizer does—it’s a slow-release mineral source.
Microbes, fungi, and natural weathering gradually make the minerals available, so benefits build up over seasons rather than instantly.
Apply during soil preparation or at planting time.
Work into the topsoil (5–10 cm deep) or spread on top as part of a mulch layer.
Typical rates: 1–2 kg per m² for initial application, lighter top-ups annually.
Combine with compost for faster microbial activity and better integration.
