Hardcover. Etat : New. This is to serve as a valuable text- and reference book to the undergraduate and postgraduate students, and researchers in the field of agriculture, horticulture, food science, home science, forestry, biochemistry, biotechnology, agricultural chemicals and other allied fields. The book contains 9 different chapters, precisely and comprehensively covering various analytical and instrumental techniques. The chapters 1-3 of the book describe the fundamental aspects which are most important for the learners to know and to conduct any experiment in chemical and biochemical fields. The remaining chapters emphasize on various advanced techniques that are employed for separation of individual components from a mixture of substances, and their qualitative and quantitative estimation. Chapter 1 deals with the basic concepts on acid-base theories, pH, and buffer solution preparation and the mechanism of its action. Chapter 2 provides the preliminary knowledge on standard solutions and their preparations, and various titrimetric methods. Chapter 3 provides a glimpse on indicator chemistry: their types, mechanism and indicator solution preparation. Chapter 4 comprehensively explores centrifugation technique, its principle and types, rotors, etc. Chapter 5 introduces the readers to different types of electrophoresis technique used primarily for biochemical analysis including their principles and applications. Chapter 6 deals with various spectroscopic techniques that include basic theory of spectrophotometry, UV-VIS spectrophotometry, fluorimetry, nephelometry and turbidimetry, infrared spectroscopy, atomic absorption spectroscopy, flame photometry and atomic fluorescence spectroscopy along with their applications. Chapter 7 concentrates on mass spectrometry with a detailed explanation on various sources of ionization and mass analyzers. Chapter 8 pertains to various chromatographic separation procedures including paper chromatography, thin layer chromatography, column chromatography, ion exchange chromatography, gel filtration chromatography, affinity chromatography, high performance liquid chromatography and gas liquid chromatography. Each type of chromatographic separation technique includes their basic principle, instrumentation and applications. Lastly, Chapter 9 covers the importance and application of radioisotopes, types of particles and their properties, radioactive decay and disintegration rate, interactions of radiations with matter, radioactivity detection techniques and their instrumentation etc. Each chapter of the book contains a few model questions to help the learners self-assess their grasp of the subject as well as practice the frequently asked questions in various competitive examinations. Necessary references have been incorporated to motivate readers for further exploration. …

Hardcover. Etat : New. Contents: 1. Earth and earth crust chemical and elemental composition. 2. Soil forming rocks and minerals. 3. Weathering processes and soil formation. 4. Soil reactions (pH) and its buffering capacity. 5. Soil organic matter and its chemistry. 6. Soil colloids and their chemistry. 7. Plant nutrients, their sources and transformation chemistry in soil. 8. Ion exchange reactions and chemical equilibria in soil. 9. Soil biology and chemistry of related soil processes. 10. Problem soils. 11. Chemistry of acid soils. 12. Chemistry of salt-affected soils. 13. Chemistry of submerged or waterlogged soil. 14. Soil, air and water pollution. This book is primarily supposed to be used as a textbook on Soil Chemistry and Plant Nutrients. This has been written to fulfil the requirements of the students studying agriculture at the undergraduate level of all agricultural Universities or other educational institutes in India and abroad. However, postgraduate student and research scholars of soil science and allied field may also equally be benefitted. This book is dealing with fourteen chapters covering chemical and elemental composition of Earth and Earth crust; rocks and minerals, their weathering processes leading to soil formation; soil reactions (pH) and its buffering capacity; soil organic matter; inorganic soil colloids such as silicate clays and others; essential plant nutrients, their sources and transformation chemistry in soil; organic manures, chemical fertilizers and biofertilizers, ion exchange reactions and chemical equilibria in soil, soil biology and chemistry of related soil processes; soil erosion and its impact on soil fertility; problem soils such as acid soil, salt-affected soil, submerged or waterlogged soil. All these aspects have been dealt from chemistry point of view with sufficient explanation and mechanisms of certain processes, wherever it is applicable, in order to make the subject more meaningful, logical, simple, and understandable to the learners as well as the teachers. Finally, it deals with present day burning issue of environmental pollution due to intensive and extensive agricultural practices leading to soil contamination with pesticides, fertilizers, and other hazardous compounds which, in turn, cause air and water pollution too. With my vast teaching and research experience that started from 1985, The book has been prepared in such a manner that students may find their all sorts of queries in soil science from chemistry point of view through a holistic approach. The chapters have been arranged systematically, so that the readers will enter the domain of soil chemistry in a proper way step by step. Model questions, both subjective and objective type, have been incorporated at the end of each chapter; so that students may be able to get an idea about the pattern of questions which are being asked during various competitive examinations.…
