VRD: Volcanic Rock Dust

Found deep within ultra-rich volcanic basalt deposits in the microclimates of tropical Indonesia – VRD: Volcanic Rock Dust is sourced from the same quarries that locals use to fertilise their crops. VRD is a horticultural-grade fertiliser, bountiful in essential trace minerals which invigorate composting and allow plants to thrive.

 

All Organic Start products are run through phytosanitary checks and an organic vector elimination process prior to export, which guarantees their safety and efficacy. The nutrient-rich volcanic rock is run through five screens, equivalent to 200-mesh filters, and then superheated to guarantee product cleanliness, consistency and bioavailability.

 

Volcanic Rock Dust is applicable to a range of organic growing programs. It is a NOP Certified Organic product in the United States, and an ideal tonic for wormeries. VRD can be used in gardens, containers and raised beds, for vegetables, fruits, herbs, flowers, vines, trees and shrubs. VRD is safe to use with all plants.
