Basalt Rock Dust

Description

Basalt Rock Dust, also known as volcanic rock dust, is rich in micronutrients like calcium, iron, magnesium and manganese. Used to add minerals to deficient soils and as a base for micro nutrients in living soilless mediums. Basalt helps increase root growth and boost crop yields.

High silica content increases rigidity of plants, making them resistant to pests, drought and disease.
