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. 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. Typically applied at 10-20 pounds per 100 ft2 of garden space or 1 cup per cubic foot of potting soil.
