What are the ingredients in Terra Preta soil?
The terra preta soils were generated by pre-columbian native populations by chance or intentionally adding large amounts of charred residues (charcoal), organic wastes, excrements and bones.

Is biochar the same as terra preta?
Think of terra preta as the first biochar. The combination of carbon and organic matter created in the Amazon Basin thousands of years ago still nourishes these soils today. Terra preta is the name of a carbon and nutrient rich soil, which has been produced by pre-Columbian cultures by the incorporation of manure, charcoal and bones into the grounds. Today, this concept has been rediscovered for the treatment of human faeces and household wastes (e.Making terra preta soil from kitchen waste when the compost bin is full, compress the contents and seal the bin. Leave to mature until no organic matter is visible (around 6 months).
