Basalt is an igneous rock created through the cooling and solidification of magma and lava. When ground down into a fine powder, it makes a very good soil improver. Igneous rocks like basalt and granite have the highest mineral content, with basalt providing a greater balance of nutrients for optimal plant health and vitality.
Basalt, or rock dust, continues to deliver a steady flow of nutrients over time, even as it decomposes. Basalt’s slow-release benefits make it an effective way to minimize deficiencies, particularly with fast-growing crops that
