Terra Preta Gardens and Amazonian Civilization Origins. Amazonian terra preta black soil represents ancient man-made gardens found throughout the Amazon These cultivation pockets are at least 10,000 years old The Amazon was not entirely cultivated but contained thousands of cultivated pockets

Amazonian terra preta black soil represents ancient man-made gardens at least 10,000 years old throughout the Amazon, containing thousands of cultivation pockets. Indigenous people today know these locations and practice seasonal farming there, yet modern science cannot recreate the soil composition. The Amazonian city Kakuruni was discovered in the 1970s with an estimated population of 1 million. This challenges assumptions about pre-Columbian population distribution across the Americas.
