The field of humic matter research has undergone drastic changes in concepts and principles, and a second edition is now warranted to communicate these advances. This revised and updated edition continues the tradition of providing comprehensive coverage of the genesis, extraction, properties, and impacts of humic matter on agriculture, industry, and the environment. Chapters examine organic matter; present concepts of humus versus humic matter; and explore the nature and distribution, chemical composition, characterization, electrochemical properties, agronomic and industrial applications, and medicinal and pharmaceutical applications of humic substances.

Helps to learn the secrets of soil chemistry and its role in agriculture and the environment. This book also helps to examine the fundamental laws of soil chemistry, how they affect dissolution, cation and anion exchange, and other reactions.

Offers comprehensive information on environmental issues in soil science. This work includes such topics as effects of agricultural operations on changing soils properties and the environment, beneficial organisms and their role in nutrient cycling, organic farming, advances in agricultural biotechnology, soil contamination, and soil conservation.

Explores the climate, soil zones, and altitudinal variation in soil formation. This book discusses the genesis, properties, classification, and land use of the soils. It covers the development of soil science in Indonesia, the geography and geomorphology of the archipelago, climate, vegetation, and mineralization and humification processes.
