Available in PDF, EPUB and Kindle. Book excerpt: The Kjeldahl Method for Organic Nitrogen volume presents a broad and comprehensive survey of the method as applied to natural products and organic nitrogen compounds. The quantitative determination of an element as widely distributed as nitrogen is of great importance, and the truth of this is borne out by the tremendous amount of literature published throughout the years. The analysis of nitrogen can be divided into two classes: inorganic and organic. This book is concerned only with organic nitrogen compounds, and specifically their determination by the Kjeldahl method. The book opens with a chapter on the historical background and the work leading to the evolution of the method. This is followed by separate chapters that discuss each of the several divisions of the method, e.g., salt addition, reduction, oxidation, catalysts, distillation.

Book excerpt: Semimicro Quantitative Organic Analysis focuses on the analytical phase of research and chemistry of natural products, as well as analysis of gases and methods used in identifying iodine and other substances. The manuscript first offers information on the determination of carbon, hydrogen, and nitrogen, and the use of Kjeldahl and Dumas methods in the determination of nitrogen. The book also ponders on the determination of halogens, including the use of ethanolamine-sodium, Carius, and sodium peroxide fusion methods and the Liepert volumetric method for iodine. The publication discusses the determination of sulfur and phosphorus, as well as the alkali-nitrate fusion method for converting organic phosphorus to orthophosphate and Woy's procedure for weighing phosphorus as phosphomolybdic anhydride. The text also reviews the determination of methoxyl and ethoxyl and acetyl groups; determination of neutralization equivalent and molecular weights; and determination of volatile fatty acids. The manuscript is a dependable reference for readers interested in the chemistry of natural products.

Available in PDF, EPUB and Kindle. Book excerpt: Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis was first introduced in 1954 the considerations were: 1. the dependence of scientific progress in biology on the improvement of ex isting and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized jour nals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete that it is dif ficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be just as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a way that made description, as applied to plant material, com plete in itself with little need to consult other publications. Contribution authors have attempted to follow these guidelines in this New Series of volumes.

Book excerpt: Soil Management and Climate Change: Effects on Organic Carbon, Nitrogen Dynamics, and Greenhouse Gas Emissions provides a state of the art overview of recent findings and future research challenges regarding physical, chemical and biological processes controlling soil carbon, nitrogen dynamic and greenhouse gas emissions from soils. This book is for students and academics in soil science and environmental science, land managers, public administrators and legislators, and will increase understanding of organic matter preservation in soil and mitigation of greenhouse gas emissions. Given the central role soil plays on the global carbon (C) and nitrogen (N) cycles and its impact on greenhouse gas emissions, there is an urgent need to increase our common understanding about sources, mechanisms and processes that regulate organic matter mineralization and stabilization, and to identify those management practices and processes which mitigate greenhouse gas emissions, helping increase organic matter stabilization with suitable supplies of available N. Provides the latest findings about soil organic matter stabilization and greenhouse gas emissions Covers the effect of practices and management on soil organic matter stabilization Includes information for readers to select the most suitable management practices to increase soil organic matter stabilization

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive survey of the Kjeldahl method and its modifications. It covers all relevant topics, including sample digestion and its variables, distillation and determination of ammonia, equipment development, and concludes with a review of the literature published on the method. Since its introduction in 1883, the Kjeldahl method has been an essential analytical tool for nitrogen determination in research, academic and industrial laboratories. This makes the history of the Kjeldahl method of outstanding relevance to graduate students, postgraduate students, researchers, teachers, and laboratory staff in the fields of analytical chemistry, food/feed analysis, animal/human nutrition, soil/water analysis, and so forth. "This method has probably been applied in one modification or another to every possible form of nitrogen, and in perhaps more laboratories than almost any other single type of analytical method" (Kirk, 1950).

Available in PDF, EPUB and Kindle. Book excerpt: A guide to soil analysis for chemists and environmental scientists Soil-so essential to life on earth-is one of the most complicated of materials. A complex mixture of inorganic and organic solids, liquids, and gases, soil presents a challenging material for analysis, especially for researchers who are not specialists in soil chemistry. This clear, broadly applicable reference provides chemists and environmental scientists with the background they need to analyze soil, interpret their findings, and develop new analytical methods for soil. Introduction to Soil Chemistry will also be valuable to the soil scientist confronting soil analyses that appear to be incorrect or do not work. Introduction to Soil Chemistry: Analysis and Instrumentation investigates the most important soil characteristics that impact analysis and the procedures, chemicals, and equipment used to determine the composition and quantity of soil constituents. It also discusses factors that interfere with accurate soil analysis. Chapters examine such topics as: * Large features-horizons, peds, soil color, and soil naming * Microscopic to atomic orbital description of soil chemical characteristics * Soil components in combination * The biological and organic components in soil * The soil solution and soil air * Electrical measurements, titration, and extraction * Spectroscopy and chromatography * Speciation This book is enhanced by numerous examples within the text, which provide the reader with a practical understanding of various analytical procedures, along with the pitfalls and interferences that may be encountered. Bibliographies and additional resources appear at the end of each chapter.
