About Basalt Rock Dust
Basalt deposits are formed by the rapid cooling of magma during volcanic events. Our source is the ancient lava fields of central Oregon. Basalts are mined for a wide variety of applications. What would in some cases become a waste product, the rock dust instead becomes an advantageous addition to our gardens.
A large diversity of minerals are found in the ground dusts of these rocks. Basalt contains high levels of phosphorous as well as potassium along with generous portions of calcium, magnesium, manganese and iron. Another often neglected but essential element found in high levels in basalt rock dust is silica. Silica strengthens cell walls aiding in resistance to stress factors.
