UNDO Carbon Ltd

At UNDO, we supply and spread crushed silicate rock such as basalt on agricultural land free of charge or well-subsidised. This enriches soil health while removing carbon dioxide from the atmosphere through a process called enhanced rock weathering. 

This mineral-rich rock has been applied to soil for hundreds of years due to its benefits for soil fertility, soil biology, crop yield and health. Our basalt is suitable for all crops including pasture and has been approved for use in organic farming systems. 

As the crushed silicate rock breaks down it releases magnesium, calcium, potassium and other nutrients, reducing the need for fertilisers. It can also help manage and maintain the target pH of the soil, reducing the need to lime as frequently.
