In my part of the world (Northeastern North America), there is a product widely sold as “black earth” that is very popular with gardeners. Terra mulata soils are more fertile than surrounding soils but less fertile than terra preta, and were most likely intentionally improved using charcoal.

A product of indigenous soil management and slash-and-char agriculture,[3] the charcoal is stable and remains in the soil for thousands of years, binding and retaining minerals and nutrients.[4][5]. [35], Terra preta soils also show higher quantities of nutrients, and a better retention of these nutrients, than surrounding infertile soils. [28] The variations in Amazonian dark earths prevent clearly determining whether all of them were intentionally created for soil improvement or whether the lightest variants are a by-product of habitation. [8][9] Terra preta is less prone to nutrient leaching because of its high concentration of charcoal, microbial life and organic matter. If you really could get your hands on true black earth at a reasonable price, it would be wonderful: pretty much the ideal garden soil! Our topsoil is 100% natural with no additives.

People also ask, is black soil good for grass? Black earth typically contains a high amount of nutrients, and it helps flower beds keep those nutrients as well as moisture. [35], The chemical structure of charcoal in terra preta soils is characterized by poly-condensed aromatic groups that provide prolonged biological and chemical stability against microbial degradation; it also provides, after partial oxidation, the highest nutrient retention. By convention, charcoal is considered to be any natural organic matter transformed thermally or by a dehydration reaction with an oxygen/carbon (O/C) ratio less than 60;[29] smaller values have been suggested. After all, plants rely on topsoil, the uppermost layer of the earth's surface, for water and necessary nutrients.
