Available in PDF, EPUB and Kindle. Book excerpt: Soil Health and Intensification of Agroecosystems examines the climate, environmental, and human effects on agroecosystems and how the existing paradigms must be revised in order to establish sustainable production. The increased demand for food and fuel exerts tremendous stress on all aspects of natural resources and the environment to satisfy an ever increasing world population, which includes the use of agriculture products for energy and other uses in addition to human and animal food. The book presents options for ecological systems that mimic the natural diversity of the ecosystem and can have significant effect as the world faces a rapidly changing and volatile climate. The book explores the introduction of sustainable agroecosystems that promote biodiversity, sustain soil health, and enhance food production as ways to help mitigate some of these adverse effects. New agroecosystems will help define a resilient system that can potentially absorb some of the extreme shifts in climate. Changing the existing cropping system paradigm to utilize natural system attributes by promoting biodiversity within production agricultural systems, such as the integration of polycultures, will also enhance ecological resiliency and will likely increase carbon sequestration. Focuses on the intensification and integration of agroecosystem and soil resiliency by presenting suggested modifications of the current cropping system paradigm Examines climate, environment, and human effects on agroecosystems Explores in depth the wide range of intercalated soil and plant interactions as they influence soil sustainability and, in particular, soil quality Presents options for ecological systems that mimic the natural diversity of the ecosystem and can have significant effect as the world faces a rapidly changing and volatile climate

This book was released on 2013-02-27 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural processes and human activities alter the properties and quality of soils over time. Nowadays, the growing interest in soil protection prompts abundant research to estimate soil quality in wide-ranging environmental scenarios. The assessment of soil quality entails the evaluation of the capability of a soil to perform its functions in present scenarios but also how those functions can be preserved for future land use. Currently, soil processes, physical, chemical, and biological properties are recognized as indicators to estimate soil quality. Soil processes and current trends in quality assessment provides a wide depiction of current research conducted in soil quality assessment, encompassing general studies on soil processes, evaluation of significant indicators of soil quality such as soil organic matter dynamic and soil-plant interaction, while presenting diverse strategies for soil fitness amelioration.

Book excerpt: This book which is edited by Dr Bao-Luo Ma, a senior research scientist from Agriculture and Agri-Food in Canada, includes contributions from more than twenty-eight scientists in this dynamic field from around the world. This book synthesises the latest innovations and integrated knowledge from science disciplines as diverse as agronomy, soil science, ecology, economy, and social sciences. The global population is projected to reach nine billion by mid-century. Questions continue to arise concerning the ability of the agriculture sector to keep pace with the demands for food, feed, fibre and fuel of an increasing population in the near future, as well as finding a way of sustaining both the production system and the environment. Crop rotations, an ancient practice that has gained renewed interest in recent years, involve growing different crop species/varieties on the same piece of land in consecutive growing seasons (years). The direct and indirect benefits of this practice to the production system and the environment have been recognised for millennia. In recent years, it has been documented that crop rotations coupled with conservation tillage has enhanced the physical, chemical and biological properties of soil, improved seasonal nitrogen availability, and provided nitrogen inputs through symbiotic nitrogen fixation by legumes. This strategy can also lead to a better balance of plant nutritional requirements and a shift in soil mycorrhizal populations, interrupt insect populations, increase root activity, reduce disease severity, enhance environmentally-friendly biodiversity, and lower per-area greenhouse gas emissions or per-yield based carbon footprints. This book serves as one of the most recent and valuable reference on these multi-disciplines, and targets audiences at the undergraduate and graduate level, including crop, soil and agronomy scientists as well as environment scientists and policy-makers.

Available in PDF, EPUB and Kindle. Book excerpt: Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Download or read book Long-term Impact of Tillage and Cropping Managements on Soil Hydro-physical Properties and Yield written by Amin Nouri Gharahassanlou and published by . This book was released on 2017 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil physical and hydraulic properties control the major soil functions related to the imbibition, transmission and retention of water, air, heat and nutrients. Adoption of no-tillage in Tennessee through the last decades has considerably decreased the fluvial soil losses. However, the long-term effect of no-tillage on soil hydro-physical properties and its interaction with companion practices such as cover crops and crop sequence has not been fully discovered. In this project, three long-term experiments located in West Tennessee Research and Education Center in Milan and Jackson, TN were studied in 2015 and 2016 for soil hydro-physical properties. The effect of 34 years of tillage, fertilization and cover crop, 15 years of crop rotation on no-tillage with winter fallow and 37 years of a range of tillage intensities and no-tillage with and without cover crop on soil physical properties were assessed. Relationship between soil physical properties were determined and by relating the soil physical properties to corn, cotton and soybean yield and long-term yield stability, the most effective cropping and tillage managements were identified. Long-term no-tillage substantially improved soil aggregation, water infiltration and transmission and cotton yield than conventional tillage. Effect of cover crops on measured soil physical properties were less evident than the effect of no-tillage. However, planting hairy vetch and wheat cover crops improved the soil aggregation and increased the water infiltration and transmission significantly compared with no cover crop. No-tillage planted with hairy vetch cover crop experienced significantly higher quasi-steady and cumulative infiltration compared with the other treatment combinations in both years. Cropping corn, cotton and soybean in double cropping sequences did not favor soil in improved physical quality than monoculture while existence of corn in cropping system either as continuous cropping or in sequence improved soil physical quality. Corn rotated with soybean and cotton increased yield and decreased the long-term variance in soybean yield. Under sub-humid climate of Tennessee with relatively high decomposition rate of organic matter, the magnitude of residue turnover and below-ground root activity was found to be key factors increasing the no-tillage potential for additional improvement in soil quality and yield.

This book was released on 2016-08-01 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is the most important natural non-renewable resource developed over a longer period of time due to weathering of rocks and subsequently enrichment of organic matter. Soil provides habitat for numerous microorganisms and serves as a natural medium for plant growth, thereby providing the plants with anchorage, nutrients and water to sustain the growth. Soil also serves as a universal sink for all types of pollutants, purifies ground water and is a major reserve of carbon in the universe. The role of soils to provide ecosystem services, maintenance of environmental/human health and ensuring the food security makes it as the most important and basic natural resource. Soil Science helps us to elaborate and understand how the soils provide all these services. Soil Science also provides us the basic knowledge dealing with the origin of the soil parent material, weathering of parent material and the formation of soils, morphological, physico-chemical and biological features of soils, classification of soils and role of soils in the provision and maintenance of ecosystem services, food security and environmental quality. This book encompasses the various processes, functions and behaviour of soils very comprehensively to acquaint the students of soil, plant and environmental sciences about their role to perform different agricultural and environmental functions.
