SOBAC is based in southern France and their products Bacteriolit and Bacteriosol are made up of a complex of micro-organisms which improves the level of micro-life in the soil, allowing the soil to fulfil its full natural cycle. It was developed by Marcel Mezy, a French farmer, in the eighties.

SOBAC is a very unique product which works with natural soil processes to help improve the soil. It helps to transform organic matter into humus. Any positively charged element is naturally fixed on to the clay humic complex via the law of attraction as the clay humic complex is negatively charged.
