What Is Terra Preta?

Terra Preta is a very dark soil that is found in the Amazon forests. This soil is an amazing discovery to scientists like Johannes Lehmann because the soil is very unique compared to other soils found in the same area. According to his research, these soils could have been in the Amazon anywhere from 500 to 8000 years which is a really big gap. Scientist believe that the soil was fertilized by human remains which were left to sit in the forest overtime. What is interesting about Terra Preta is that scientist found information recently and came up with the conclusion that this soil was made from trees, pots, and foods that the Amazonian people left in the forests which eventually burned and turned into biochar.
