Download or read book Soil Compaction in Crop Production written by B.D. Soane and published by Elsevier. This book was released on 2013-10-22 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a global review of the mechanisms, incidence and control measures related to the problems of soil compaction in agriculture, forestry and other cropping systems. Among the disciplines which relate to this subject are soil physics, soil mechanics, vehicle mechanics, agricultural engineering, plant physiology, agronomy, pedology, climatology and economics. The volume will be of great value to soil scientists, agricultural engineers, and all those involved with irrigation, drainage and tillage. It will help to facilitate the exchange of information on current work throughout the world, as well as to promote scientific understanding and stimulate the development, evaluation and adoption of practical solutions to these widespread and urgent problems.

Book excerpt: The World Resources Institute (WRI) and United Nations Food and Agriculture Organization (FAO) estimate that global agricultural food production will need to increase 56% between 2010 and 2050 to meet projected caloric demands of the growing population. Given the finite amount of global land area as well as the impacts agricultural land-use and production have on greenhouse gas emissions (GHGs), achieving this increase in consonance with climate change reduction goals presents a formidable challenge. In the past, large yield improvements have been realized from genetically modified seeds, synthetic fertilizers and pesticides, increased mechanization, and improved irrigation, but these innovations have also brought negative side effects. For example, the increasing weight of mechanized farm equipment has led to significant man-made soil compaction. Soil compaction is the increase in bulk density, or reduction of air pore space, in a soil matrix, and it can lead to restricted root growth, poor water and nutrient infiltration, and reductions in yield. Specifically, man-made compaction has been estimated to lead to 15-20% reductions in crop yield, leading to $40-45 Billion in annual financial losses in the United States alone. Mechanical tillage is one of the most common remedies for loosening compacted soil, but the process damages soil structure and overall soil health, making it a solution that should optimally be used sparingly, only in areas where soil is severely compacted. A key challenge to enabling this, however, is compaction sensing and mapping at the field scale. In response to this challenge, a research project was undertaken through MIT Beaver Works, a collaboration with MIT Lincoln Laboratory, to explore systems-based solutions for real-time soil compaction sensing and mapping. Through that work, a high-level system design for measuring soil compaction at the field scale was proposed based on electromagnetic sensing, including the use of ground penetrating radar (GPR) and electromagnetic induction (EMI) sensors. This thesis aims to address the highest risk aspects of the proposed approach through modelling, laboratory testing, and field testing, progressing theoretical results into increasingly more realistic settings to better understand practical limitations and potential challenges with the technical approach.

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
