Terra Preta

Terra Preta, or "black earth," is a type of fertile soil found in the Amazon rainforest, created by ancient Indigenous peoples. It is rich in nutrients and organic matter, making it exceptionally good for farming. The soil contains charcoal, bones, and other organic materials, which improve its ability to retain water and nutrients. Terra Preta stands out because of its dark color and high fertility, contrasting with the surrounding poor, acidic soils. It showcases ancient agricultural practices and has potential implications for sustainable farming today, as scientists study how to replicate its beneficial properties.
