Agricultural Basalt Rock Dust 2kg

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:

Purpose

  • 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.

How It Works

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.

Application Tips

  • 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.
