Our April guest speaker will be Guy Lewington, the Chief Executive Officer of Mt Sylvia Soil Conditioners. Guy will tell us about the Soil Conditioners produced by their company and the research they have carried out into the uses and effectiveness of these products. Guy has an honours degree in Geology, and diplomas in Mineral Economics and Organic Agriculture. He is also a member of the Australian Institute of Mining and Metallurgy.

He was instrumental in the discovery and development of large gold mines in Western Australia including Kanowna Belle, Sunrise Dam and Nimary. He spent seven years as an organic macadamia grower in northern NSW. As a farmer he renewed his friendship with Martin I’Ons who owned a neighbouring farm. Together they became increasingly fascinated with diatomaceous earth as a fertilizer and soil conditioner and as geologists recognized the hidden potential of the high quality product at Mt Sylvia.
