Chernozem (Template:Lang-ru, black soil), also known as "black land" or "black earth", is a black-coloured soil containing a very high percentage of humus — 3% to 15%, and high percentages of phosphoric acids, phosphorus and ammonia. Chernozem is very fertile and produces a high agricultural yield.
There are two "Chernozem belts" in the world: from Northeast Ukraine across the Black Earth Region and Southern Russia into Siberia, and in the Canadian Prairies. Similar soil types occur in Texas. It has a large depth, often more than 40 inches and up to 250 inches (6 metres) in Ukraine. The terrain can also be found in small quantities elsewhere (for example, on 1% of Polish territory).
Chernozemic soils are a soil type in the Canadian system of soil classification and the United Nations' FAO soil classification.
