Terra Preta
Terra Preta
Terra Preta, also called black soil, is a method developed by the Indians thousands of years ago, to make soil more fertile. For decades, biomass, ashes, bones, human faecal matter and much more have been added to the soil as fertilizer. Many gardeners refer to Terra Preta as the new secret weapon in the garden and there are many rumours surrounding the miracles of the Indian earth. Agronomists disenchant the myth, however: From their point of view, its sale in specialist markets is not only overpriced, but largely superfluous.
