Not to be confused with regular rock phosphate, more ethical than Guano. Soft rock phosphate is a bio-friendly, colloidal clay-based calcium phosphate that can never lock up, in stark contrast to other phosphate sources. This exceptional fertiliser includes 8–9% phosphorus, 19.3% calcium, 26% silicon and a rich lode of trace elements. A microbe-friendly phosphorus, which is an integral part of our soil regeneration program. This is one of the few phosphate sources that does not have problems with high levels of the heavy metal cadmium.
