Preface
This text is primarily meant to cater the need of undergraduate and postgraduate student of Chandra Sekhar Azad University of Agriculture and Technology, Kanpur and also other Agricultural Universities/Institutes in India and is expected to be of help to teachers and researchers as well. An endeavour has been made to provide sufficient theoretical background on the subject matter to ensure that the procedures are not followed merely to obtain a numerical answer. The main aim of preparing this practical manual is to provide the post graduate students of Agriculture a simple exposition of the subject. It is primarily designed to cover the syllabus of soil science. It is expected to help the students in examination of four major areas viz. Soil Physics, Soil Chemistry, Fundamental Concepts of Instrumental Techniques and Fundamental Concepts of Analytical Chemistry. Each topic is presented in a lucid and concise manner furnishing details of reagent preparation and stepwise procedure, outlining precautions and additional notes wherever necessary. The principles have been discussed briefly and theories explained well with mathematical derivations and chemical equations as and when required. The analytical methods described in this text are either being widely used or have been accepted throughout as standard. Various methods have been explained in a simple and easily understandable language comprising of principle with equipment's and apparatus, procedure, observations and calculations.
Inspite of best efforts by the authors, the text may still have some discrepancies. Suggestions for improvement from the readers will be highly appreciated
