Available in PDF, EPUB and Kindle. Book excerpt: "This publication describes how to estimate lime application rate and lists criteria for choosing liming materials (source), lime application method (placement), and how often to apply lime (frequency). Lime application rate is determined using the lime requirement test (SMP buffer method). For established perennial or no-till crops, a top-dress lime application (1 to 2 t/a) may be beneficial. When very different soils are present within a field, variable-rate lime application is usually advantageous. Liming materials vary in effectiveness. The carbonate in traditional aglime (calcium or magnesium carbonate) reacts with soil acidity to neutralize it. Liming materials have very limited movement into the soil without incorporation. Tillage increases effectiveness of all lime materials by mixing them into the rooting zone. Evaluate liming materials based on effectiveness (lime score) and cost. Calculate product cost per ton of 100-score lime. By-product lime products can be a cost-effective substitute for traditional aglime. Their characteristics should be evaluated carefully. For certified organic crops, use only lime approved by your certification agency. Lime application method (placement) takes two forms. Lime is either applied and left on the soil surface or incorporated. In the absence of tillage, soil pH increases only in the top inch or 2 of soil since lime's limited solubility means that the liming material must contact acidic soil before it will react and change soil pH. Frequency of lime application is determined primarily by cation exchange capacity (CEC) and crop management practices, especially N fertilizer rate. Soil pH declines faster in sandy (low CEC) soils than in soil with moderate to high clay content. The typical rate of pH decline is approximately 0.1 pH unit per year when 100 lb ammonium N/a is applied. For annual crop rotations, apply lime about a year before planting the crop that is most sensitive to soil acidity. For perennial crops, soil test and apply lime prior to tillage for crop establishment."--Page 2.

This book was released on 2008-09-16 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.

Available in PDF, EPUB and Kindle. Book excerpt: "World War II was the largest and most destructive conflict in human history. It was an existential struggle that pitted irreconcilable political systems and ideologies against one another across the globe in a decade of violence unlike any other. There is little doubt today that the United States had to engage in the fighting, especially after the Japanese attack on Pearl Harbor on December 7, 1941. The conflict was, in the words of historians Allan Millett and Williamson Murray, "a war to be won." As the world's largest industrial power, the United States put forth a supreme effort to produce the weapons, munitions, and military formations essential to achieving victory. When the war finally ended, the finale signaled by atomic mushroom clouds over Hiroshima and Nagasaki, upwards of 60 million people had perished in the inferno. Of course, the human toll represented only part of the devastation; global environments also suffered greatly. The growth and devastation of the Second World War significantly changed American landscapes as well. The war created or significantly expanded a number of industries, put land to new uses, spurred urbanization, and left a legacy of pollution that would in time create a new term: Superfund site"--

Available in PDF, EPUB and Kindle. Book excerpt: Silicon, considered to be the second most abundant mineral element in soil, plays an important role in the mineral nutrition of plants. A wide variety of monocot and dicot species have benefited from silicon nutrition, whether direct or indirect, when they are exposed to different types of abiotic and or biotic stresses. Besides the many agronomic and horticultural benefits gained by maintaining adequate levels of this element in the soil and also in the plant tissue, the most notable effect of silicon is the reduction in the intensities of a number of plant diseases caused by biotrophic, hemibiotrophic and necrotrophic plant pathogens in many crops of great economic importance. The aim of this book is to summarize our current understanding of the effects of silicon on plant diseases. The chapters address the dynamics of silicon in soils and plants; the history of silicon in the control of plant diseases; the use of silicon to control soil-borne, seed-borne and foliar diseases in monocots and dicots; the mechanisms involved in the host resistance against infection by plant pathogens mediated by silicon as well as the current knowledge at the omics level, and finally, highlights and prospects for using silicon in the future.
Download or read book Applied Manure and Nutrient Chemistry for Sustainable Agriculture and Environment written by Zhongqi He and published by Springer Science & Business Media. This book was released on 2014-04-07 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the rapid increase in world population and improving living standards, the global agriculture sector is confronting with challenges for the sustainability of agricultural production and of the environment. Intensive high-yield agriculture is typically dependent on addition of fertilizers (synthetic chemicals, animal manure, etc.). However, non-point nutrient losses from agricultural fields due to fertilization could adversely impact the environment. Increased knowledge on plant nutrient chemistry is required for improving utilization efficiency and minimizing loses from both inorganic and organic nutrient sources. For this purpose, the book is composed of 19 chapters that highlight recent research activities in applied nutrient chemistry geared toward sustainable agriculture and environment. Topics of interest include, but are not limited, to speciation, quantification, and interactions of various plant nutrients and relevant contributories in manure, soil, and plants. This book outlooks emerging researchable issues on alternative utilization and environmental monitoring of manure and other agricultural by products that may stimulate new research ideas and direction in the relevant fields.
Download or read book Advances in Soil Science written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Advances in Soil Science is to provide a forum for leading scientists to analyze and summarize the available scientific information on a subject, assessing its importance and identifying additional research needs. A wide array of subjects has been addressed by authors from many countries in the initial ten volumes of the series. The quick acceptance of the series by both authors and readers has been very gratifying and confirms our perception that a need did exist for a medium to fill the gap between the scientific journals and the comprehensive reference books. This volume is the first of the series devoted entirely to a single topic soil degradation. Future volumes will include both single-topic volumes as well as volumes containing reviews of different topics of soil science, as in the case of the first ten volumes. There are increasing concern and attention about managing natural re sources, particularly soil and water. Soil degradation is clearly one of the most pressing problems facing mankind. Although the spotlight regarding soil degradation in recent years has focused on Africa, concern about the degradation of soil and water resources is worldwide. The widespread con cern about global environmental change is also being linked to severe problems of soil degradation. Therefore, we are indeed pleased that the first volume of the series devoted to a single topic addresses such an impor tant issue. The current volume is also the first of the series involving a guest editor.

Download or read book The Soil Resource written by Hans Jenny and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: change is simply described by the rate of income and rate of loss. Our home's energy budget, our firm's inventory, our nation's debt, and humanity's numbers all have accounts that change at rates that are equal to the inputs minus the outputs. Jenny's "system view" of the soil was carried into the fertile fields of Midwestern American prairies from the laboratories of Switzerland in the late 1920s. Jenny's rate equations provided the other paradigm or world view that, I recall, brought us to the threshold of systems ecology as it later evolved in the second half of the twentieth century. As if world renown in the specialties of pedology and soil chemistry were not enough for one lifetime, excerpts below remind us that Hans Jenny has also been a perceptive outdoor field ecologist since his early Alpine expeditions with Braun Blanquet in the mid 1920s. Jenny's ecosystem studies in the pygmy forest, a further classic example of a soil-plant system "run down" over hundreds of thousands of years since its origin, continue to occupy some of the vigorous retirement time near his farm in Mendocino County. But each specific, quantitative case study, and each research area conserved (with additional hard work) for further study by future generations, fits into Jenny's coherent world view. It is that view, and its legacies of discovery and of tangible landscape preserves, which we are privileged to share with their originator in this volume.
