Christopher Cameron – Director of Production, Platinum Compost

Chris is a 4th generation Australian food producer who spent most of his first 50 years on a Western Darling Downs mixed farm that had very poor soil. The search for an effective and non-toxic way to change this started back in the 1960’s and is an ongoing process, seeking to follow Nature’s Blueprint. Once understood, the process can be made fast and effective, almost regardless of crop type, and it can allow plants to achieve full genetic potential production.
