About the Book: Analytical methods are the foundation of a scientific discipline. This text book is a comprehensive analytical manual covering the aspects of soil analysis in the major areas of Soil Physics and Soil Chemistry. An important feature of this text is that it describes not only the analytical procedures in detail, but also furnishes sufficient theoretical background on the subject matter. The fundamental principles of the analytical methods have been discussed precisely and theories explained well with mathematical treatments and chemical reactions whenever required. Contents: Instrumental Techniques : Fundamental Concepts Soil Physics Soil Chemistry Fundamental Concepts of Analytical Chemistry.
