Vasili Dokuchayev

Vasily Vasilyevich Dokuchaev (; 1 March 1846 – 8 November 1903) was a Russian geologist and geographer who is credited with laying the foundations of soil science. The Ukrainian city of Dokuchaievsk is named after him.

Overview Vasily Vasilevich Dokuchaev is commonly regarded as the father of soil science, the study of soils in their natural setting. He developed soil science in Russia and was perhaps the first to conduct broad geographical investigations of different soil types. His contribution to science figuratively "put soils on the map".

He introduced the idea that other variables could explain the geographical variations in soil type besides geological factors (parent material), such as climatic and topographic factors, and by the duration of pedogenesis (soil formation). He developed the very first soil classification, using these ideas as a starting point. His ideas were taken up by many soil scientists, including Hans Jenny.

Dokuchaev's work on soil science produced a system of soil classification that described five factors for soil formation. He arrived at his theory after extensive field studies on Russian soils in 1883. His most famous work is Russian Chernozem (1883). As a result of Dokuchaev's research, many Russian terms became part of the international soil science vocabulary (for example, chernozem, podsol, gley, solonets).

A crater on Mars is named after him, and the Dokuchaev Award, an equivalent of the Nobel Prize in the field of Soil Science, was instituted by the International Union of Soil Sciences in his honor.

Quote The scientific basis of soil science as a natural science was established by the classical works of Dokuchaev. Previously, soil had been considered a product of physicochemical transformations of rocks, a dead substrate from which plants derive nutritious mineral elements. Soil and bedrock were in fact equated.

Dokuchaev considers the soil as a natural body having its own genesis and its own history of development, a body with complex and multiform processes taking place within it. The soil is considered as different from bedrock. The latter becomes soil under the influence of a series of soil-formation factors (climate, vegetation, parent material, relief and age). According to him, soil should be called the "daily" or outward horizons of rocks regardless of the type; they are changed naturally by the common effect of water, air and various kinds of living and dead organisms.

Authored works Dokuchaev published in 1869-1901: 285 works, including 61 books and 4 maps.
