Rock Dust 4kg

Rockdust is freshly crushed volcanic rock from Collace Quarry in Perthshire Scotland. Rockdust contains 78+ minerals and trace elements that can help with poor acidic soils. This amazing product provides a slow natural release of trace minerals and elements which increase the nutrients absorbed by plants. Earthworms that deposit mineral-rich worm casts digest Rockdust thus increasing mineral availability microbial activity and natural fertility of soil or compost. Rockdust boosts soil fertility to grow bigger healthier organic fruit vegetables flowers and lawns.

Rockdust can be used with organic soil conditioners and plant foods and it contains a natural balance of lime. Do not add lime or lime-rich products as too much lime will bind up the 78+ minerals.

Rockdust can also be used as a compost activator and should be applied at the beginning of the process simply sprinkle onto each layer of green waste to encourage microbial activity increase temperature reduce odours lock in nitrogen and speed up the process. The end product is much more naturally fertile organic compost.
