Download or read book Improving Potassium Recommendations for Agricultural Crops written by T. Scott Murrell and published by Springer. This book was released on 2022 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book highlights concepts discussed at two international conferences that brought together world-renowned scientists to advance the science of potassium (K) recommendations for crops. There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health. Accordingly, this book puts forward a significantly expanded K cycle that more accurately depicts K inputs, losses and transformations in soils. This new cycle serves as both the conceptual basis for the scientific discussions in this book and a framework upon which to build future improvements. Previously used approaches are critically reviewed and assessed, not only for their relevance to future enhancements, but also for their use as metrics of sustainability. An initial effort is made to link K nutrition in crops and K nutrition in humans. The book offers an invaluable asset for graduate students, educators, industry scientists, data scientists, and advanced agronomists.

Download or read book Methods in Soil Biology written by Franz Schinner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: In terrestrial ecosystems, soil microorganisms and soil animals are essential for litter degradation, soil formation and the availability of nutrients and trace elements. The measurement of biological soil parameters allows a rapid evaluation of the effects of chemical and physical influences due to pollutants or soil management. This book introduces a number of well proved methods for the analysis of carbon, nitrogen, phosphorus and sulfur cycles. It focuses further on the determination of the number and biomass of microorganisms, algae and animals in the soil. Particular emphasis is placed on the comprehensible and complete description of the experimental procedures.

Download or read book Soil Analysis Handbook of Reference Methods written by J. Benton Jones, Jr. and published by CRC Press. This book was released on 1999-12-20 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Soil Science is an important and basic science in agriculture which deals with different domains of soil research namely, soil formation, genesis and classification, soil physics, soil chemistry, soil fertility and plant nutrition, soil biology, etc. Characterization as well as our understanding of soils requires that they are precisely analysed and described. While the physical properties of soils determine their adaptability to cultivation, chemical properties tells about their chemical environment and nutrient status to the crop production - the most important use of soils on this densely populated planet. Determination of different soil physical and chemical properties in the field or in the laboratory following suitable analytical methods is first step towards appropriate soil managements and scientific recommendations for increasing crop production.
