Terra Preta, meaning "Black Earth" in Portuguese, is a soil building technique developed by ancient Amazonian civilizations at least 7000 years ago as a solution to permanently solve the problems of poor tropical soil fertility. Large deposits of this black earth are still found today with depths of up to 2 meters. The first deposits where discovered in 1870, but it has only been in the last 10 years that significant interest and study have been initiated.
This soil is attributed to the complex civilizations that reportedly once thrived in the Amazon. Prior to the onset of diseases brought on by the western settlers, this expansive web of communities is estimated to have totaled over 100 million people. It is speculated that Terra Preta soils are what sustained them in harmony with their ecosystems.

The Amazon rainforest is one of the most amazing displays of symbiotic relationships one can experience in the world. This complex and layered eco-system thrives through the many systems and cycles that interweave through the layers of canopy, creating one of the most bio-diverse displays of life on the planet. Nature designs the most magnificent Permaculture systems – it is quite an experience to spend time in this magical place and humbly observe her teachings.

Observing the thriving and abundant rainforest, it is hard for some to comprehend why neighboring agriculture in the region experiences quite the opposite affect, but the answer is quite simple – it’s all about the soil.
