Vasily Vasilyevich Dokuchayev

Died 26 Oct 1903 at age 57 (born 17 Feb 1846).Russian geomorphologist, Vasily Vasilyevich Dokuchayev, pioneered the study of soil creation processes and their classification. Dokuchayev regarded the composition of soil as the product of the combined interaction of climate, bedrock, and organisms. Thus, he showed (1898) that different soils of different areas may result from similar bedrock material when climate is differs. In this way, he was beginning the recognition of biomes. He introduced (1883) the term chernozem for a type of rich black soil, rich in carbonates and humus, that occurs in the temperate latitudes of Russia.
