“Previously, soil had been considered a product ofphysicochemical transformations of rocks, a dead substrate fromwhich plants derive nutritious mineral elements. Dokuchaev considers the soil as a natural body having its owngenesis and its own history of development, a body with complexand multiform processes taking place within it. Bedrock becomes soil under the influence of a series of soilformationfactors: climate, vegetation, parent material, relief andage.”QUOTE Krasilnikov, N.A. 1958.Soil Microorganisms and Higher Plants
