Agricultural chemistry must be considered within the context of the soil ecosystem in which living and non living components interact in complicated cycles that are critical to all living things. The present book contains nine chapters which include introduction, environment of soil chemistry, chemical composition of the soil organic constituents of soil, constituents of soil chemistry, agricultural management in soil chemistry, soil genesis, soil landscape modeling system and soil and plant nutrients. This book serves as good source of information to agricultural scientists and students studying agriculture, soil science and agricultural chemistry, agricultural biochemistry and scholar interesting in agricultural chemistry.
