Earthlife started manufacturing microbial and rock mineral based products in 1996, after doing research into problems with poor quality soils and poor plant growth. The research indicated that Australian soils are very mineral depleted and also biologically depleted. (Re: document 264. & Earth summit report 1992)
“Rock minerals” is a generic term and in themselves are not water soluble, so it may take quite some time before you see soil or plant responses. Earthlife has developed technology and incorporated it with the combination of rock minerals and rare earths to remineralize soil structure and improve moisture and nutrient cycling systems. Earthlife rock minerals are suitable for all soil types and potting mediums.
