1 stage. As a scientific discipline soil finally emerged in the second half of the 19th century. However, the roots of formation of this discipline rooted in deep antiquity-at the beginning of the birth of agriculture (about 10 thousand years ago). In the centers of ancient civilization (China, ancient Egypt, ancient Greece, ancient Rome, 3 thousand. BC) There has been a buildup of empirical knowledge about soil, methods of its processing, properties, were the first attempts by groups of soils for use and improvement. Known for his work in the field of soil science such scholars of ancient Rome and ancient Greece, as Cato the elder, Virgil, Columella, Geradot, etc.2 stage. Middle Ages-long period of stagnation in the field of natural sciences. Some advances in the study of soil cover have been obtained in Byzantium, China, Germany, and Italy. To this period belong the early research in Russia. With the onset of decomposition of feudal society reappeared interest in studying soil in connection with the problem of power plants. In some works of that time reflected the view that feed on water plants, creating chemical compounds from water and air; the soil of the same considered as inert environment, mechanical support for plants.3 phase. Great strides in the development of the science of soil has been achieved in the period of the Renaissance (XV-XVII centuries). Were developed theories about the role of soil in plant nutrition, outlines the composition and origin of humus, improved grouping of soils. It is believed that during the revival period soil science as science was almost fully formed.4 stage. The 18TH century was marked by intensive development of Russian soil. Essential for the formation of scientific views on the ground were the work of M. Lomonosov (1711-1765)-on plant nutrition, about the origins of the black soil, etc. Mikhail Lomonosov assumed that plants feed not only water, but also thin particles of the Earth. Great attention is paid to the question of the origin of Lomonosov humus, which he considered as a product of biological processes. Teaching the elements of soil science in Russia began shortly after the death of Mikhail Lomonosov, 1770, at Moscow University in the composition course "Agricultural Economics". By the end of the 18th century became the one-size-fits-all theory of water supply plants. It was replaced by the theory of humic Albrecht Tèera. According to this theory, plants can eat only organic matter of the soil and water. A. Tèer was one of the founders and organizers of the first higher agronomics Agronomy school.5 stage. The middle of the 19th century, accumulated an extensive material for the study of soils. However, these data were highly heterogeneous and even treated to various objects. Experts in the field of agriculture and Agronomy studied predominantly arable horizon. Geologists under the ground implied a strong thickness of products of weathering of rocks. Attempts to mechanically connect the basically different directions led to the emergence of eclectic and viable agrogeologii. For soil science of the 19th century is characterized by a big rise. Begins the differentiation of science, expanding links with other sciences, formed instructional centres on preparation of specialists of agriculture.
