Top Tips for Remineralising your soil

28 July 2008

Soil Remineralisation is a simple process that can be easily achieved by anyone, from the balcony urban gardener, to the full-scale farmer.

Firstly locate source of rock dust, like the SEER Centre.  

Throughout the industrialized world the aggregate industry stockpiles rock dust as a byproduct (within the industry it is known as “rock dust,” “rock flour,” “minus #200 mesh” or  “float“).  The nearest gravel pit is the best place to ask first.  Not only is this waste material readily available but it is very affordable.  

Apply this very fine rock dust on top of the soil area that you want to remineralise. 

On a small scale it can be applied by hand while commercially it can be applied with orchard sprayers. 

Either way it is helpful if the rock dust is dry so that it takes on a powdery consistency (avoid breathing the dust, preferably wear a mask).   In most cases this fine powder can be distributed using a lime spreader or a shovel. It can be applied liberally wherever there is plant life in your garden. 

Since rock dust releases its minerals and elements slowly and because it is not a fertiliser there is no risk of over-application.

You might want to check the soil acidity before and after application - SR routinely counters soil acidity.
