Terra Preta: How the World’s Most Fertile Soil Can Help Reverse Climate Change and Reduce World Hunger by Ute Scheub, Haiko Pieplow, Hans-Peter Schmidt, Kathleen Draper
Terra preta is the Portuguese name of a type of man-made soil which is thought to have almost miraculous properties. This soil is made from a variety of kitchen or garden wastes, charcoal and earthworms, so it can be produced on every balcony or on the smallest of garden plots. This soil is able to absorb soil contaminants, retain moisture and provide nutrients for the plants, as well as replace top soil lost through erosion. This is an interesting, but somewhat long-winded and simplistic book that discusses the importance of soil and how to produce your own humus/compost/black soil or terra preta.
