The author has summarised results of the latest studies on the composition, structure and properties of humic substances, which are the largest and the most important component of organic matter of different types of soils. He has examined the group and fractional composition of humus of the principal types of soils of Russia and other countries, highlighted the dependence of their formation on bioclimatic conditions and economic activity of man. A probable structure of humic acids - the most important component of humus - has been proposed and the general theory of humification discussed. Rec...
The author has summarised results of the latest studies on the composition, structure and properties of humic substances, which are the largest and the most important component of organic matter of different types of soils. He has examined the group and fractional composition of humus of the principal types of soils of Russia and other countries, highlighted the dependence of their formation on bioclimatic conditions and economic activity of man. A probable structure of humic acids - the most important component of humus - has been proposed and the general theory of humification discussed. Recommendations have been made for forecasting change of the humus state of soils in the course of their agricultural exploitation and for improving the humus state of cultivated soils. The book is addressed to specialists in soil science, agricultural chemistry, nature conservation, agronomy, hydrochemistry, botany and soil amelioration and to students and post-graduates in these disciplines.
