Terra Preta

Terra Preta is Portuguese for “dark earth” and names the carbon-rich soils discovered in the Amazon region. Terra Preta is of anthropogenic origin and is a mixture of charcoal, solid dung, clay fragments and other domestic wastes that dates back more than 1.000 years. 

Terra Preta shows an extremely high level of organic activity. Biochar stores nutrients, which can then be taken up by the roots, as and when the plants need them. Terra Preta is able to retain moisture, helping plants to survive droughts more easily and encouraging smooth, continuous growth. Terra Preta fosters micro-bacterial activity and biodiversity.
