Download and read online Soil Analysis Handbook of Reference Methods in PDF and EPUB For more than 30 years, soil testing has been widely used as a basis for determining lime and fertilizer needs. Today, a number of procedures are used for determining everything from soil pH and lime requirement, to the level of extractable nutrient elements. And as the number of cropped fields being tested increases, more and more farmers and growers will come to rely on soil test results. But if soil testing is to be an effective means of evaluating the fertility status of soils, standardization of methodology is essential. No single test is appropriate for all soils. Soil Analysis Handbook of Reference Methods is a standard laboratory technique manual for the most commonly used soil analysis procedures. First published in 1974, this Handbook has changed over the years to reflect evolving needs. New test methods and modifications have been added, as well as new sections on nitrate, heavy metals, and quality assurance plans for agricultural testing laboratories. Compiled by the Soil and Plant Analysis Council, this latest edition of Soil Analysis Handbook of Reference Methods also addresses the major methods for managing plant nutrition currently in use in the United States and other parts of the world. For soil scientists, farmers, growers, or anyone with an interest in the environment, this reference will prove an invaluable guide to standard methods for soil testing well into the future. Features
Download and read online Soil and Water Chemistry in PDF and EPUB The second edition of a bestseller, Soil and Water Chemistry: An Integrative Approach maintains the balanced perspective that made the first edition a hugely popular textbook. The second edition includes new figures and tables, new chapters, and expanded exercises in each chapter. It covers topics including soil chemical environment, soil minerals, soil organic matter, cation exchange, oxidation-reduction, mineral weathering and solubility, surface chemistry and adsorption reactions, acidity and salinity in soil materials, and chemical thermodynamics applied to soil systems. See What’s New in the Second Edition: Extensive section that details the sources, speciation, and the general behavior of elements in soils Expanded section on crystal structure, updated phyllosillcates classifications scheme, inclusion of sepiolite-palygorskite group, and expanded x-ray diffraction section Discussion of surface runoff losses of phosphorus from soil and description of the inductivity coupled argon plasma-mass spectroscopy (ICP-MS) analytical technique for determining elemental concentrations in soil solution Coverage of the influence of redox processes on the soil chemistry of nonelectroactive elements Description of the electrokinetic phenomenon and investigation of the influence of temperature on adsorption Expanded discussion on the application of chemical thermodynamics to soil systems A solutions manual is available upon qualifying course adoption. Still one of the only texts on this subject, this book provides a comprehensive, modern, and balanced coverage of the chemical and mineralogical characteristics of soils and their chemical processes. It contains more information and topic coverage than required for an average, single-semester course. This extensive coverage is by design, giving you the latitude to pick your own essential topics while providing additional information or a more advanced treatment when needed. Figures and tables make the information accessible and each problem has been tested and is relevant and doable, but asks more of students than to simply generate a number. This format allows students to understand the concepts and recognize that their computations have physical meaning.
