This page gathers all content on Appropedia related to terra preta.
Terra preta (Portuguese pronunciation: [ˈtɛʁɐ ˈpɾetɐ], literally "black earth" in Portuguese), also known as Amazonian dark earth or Indian black earth, is a type of very dark, fertile anthropogenic soil (anthrosol) found in the Amazon Basin. In Portuguese its full name is terra preta do índio or terra preta de índio ("black soil of the Indian", "Indians' black earth"). Terra mulata ("mulatto earth") is lighter or brownish in color.
