Terra Preta, or “black earth,” is a man-made soil found in the Amazon rainforest, created over 2,000 years ago. Known for its exceptional fertility, it stands out from the nutrient-poor soils typically found in the region. Unlike other soils, Terra Preta can sustain agriculture for centuries and even regenerates itself over time.
This soil was made by mixing charcoal, bones, and organic waste into the earth through a process called pyrolysis. The charcoal improves soil structure and supports microorganisms that enhance fertility. Despite extensive research, modern science has not been able to fully replicate its unique properties.
The impact of Terra Preta is clear when comparing crops grown in it to those in natural rainforest soil. Crops in Terra Preta grow taller and healthier, while those in regular soil often struggle.
