Pages: 143-150

Abstract

History of formation and the set of methods of the new science, namely ecology of soils, are discussed. The object, subject, positions in the system of sciences and the most urgent problems are defined. The necessity to relate the ecology of soil to the sciences of the biosphere class is justified. Examples illustrating some statements, regularities and laws of the ecology of soil are described. It is shown that different components of soil humus and their ratios have specific connections with the characteristics of climate and fall within quite definite ecological ranges of the existence of soil kinds with different ratios of humic acids.
