The second chapter reviews advances in techniques used to assess and measure soil erodibility by water, such as computer aided tomography. The chapter considers the role of static and dynamic soil properties in the erosion process, as well as the challenges that have developed as a result of climate change. The third chapter assesses the impact of heavy metal contamination on soil and its consequent role in the degradation of soil health. The chapter describes the sources, impacts, indicators and remediation of heavy metal contamination, as well as the development of improved soil management practices, including effective pollution control strategies. The final chapter discusses the implementation of integrated strategies under Conservation Agriculture (CA) farming systems to restore soil productivity in degraded agricultural lands in tropical and subtropical regions in Brazil. The chapter additionally considers the adoption of CA as a tool to prevent and reverse instances of soil degradation.

This collection features four peer-reviewed literature reviews on biodiversity management practices in agriculture. The first chapter reviews biodiversity management practices and benefits in Conservation Agriculture (CA) systems. After looking at the importance of soil microorganisms, the chapter looks at how CA systems contribute to soil biological activity, particularly the way cover crops and rotations, with a no-till regime, can enrich soil and the multitude or organisms living in it. The second chapter synthesizes and reviews the published information on grass hedges and their soil benefits, to better understand the potential of grass hedges for managing water erosion as well as improving soil health in agricultural lands. The third chapter reviews research on ways of modifying the agricultural landscape to reverse the decline in a range of fauna and flora. The chapter also reviews the characteristics and types of field margins, as well as their role in agroecosystems. The chapter concludes with a discussion on managing field margins to promote insect biodiversity and rare arable plant populations. The final chapter considers the impact of agricultural intensification on agricultural landscapes, farming systems and biodiversity. The chapter highlights how hedgerows can contribute to the multifunctionality of agroecosystems in intensively-managed agricultural landscapes, focussing on improved pest regulation and enhanced pollination services.

This book uses resource economics costing approaches incorporating externalities to estimate the returns for the country's irrigation and demonstrates how underestimating the cost of water leads farmers to overestimate profits. The importance of the subject can be judged in light of the fact that India is the largest user of groundwater both for irrigation and for drinking purposes, pumping twice as much as the United States and six times as much as Europe. Despite water's vital role in ensuring economic security for the nation and farmers alike by supporting more than 70% of food production, water resource economists are yet to impress upon farmers and policymakers the true value of water and the urgent need for its sustainable extraction, recharge and use. In an endeavor to promote more awareness, the book further delineates the roles of the demand side and supply side in the economics of irrigation, and explains how the cost of water varies with the efforts to recharge it, crop patterns, degrees of initial and premature well failure and degrees of externalities. It also discusses the importance of micro-irrigation in the economics of saving water for irrigation, estimating the marginal productivity of water and how it improves with drip irrigation, the economics of water sharing and water markets, optimal control theory in sustainable extraction of water, payment of ecosystem services for water and how India can effectively recover. In closing, the book highlights the role of socioeconomic and hydrogeological factors in the economics of irrigation, which vary considerably across hard rock areas and the resulting limitations on generalizing.

The final chapter explores the implementation of foliar fertilizer sprays in agriculture for improving crop yield and quality, as well as improving plant performance under abiotic and/or biotic stress threats.

The countries that make up the MENA region display wide diversity. One of the poorest countries in the world sits alongside two of the wealthiest, whilst the region's natural resources range from immeasurable oil and gas reserves to some of the scantiest natural endowments anywhere in the world. Yet through this diversity runs a common thread: water scarcity. Now, through the impact of human development and climate change, the water resource itself is changing,bringing new risks and increasing the vulnerability of all those dependent on water. Chris Ward and Sandra Ruckstuhl assess the increased challenges now facing the countries of the region, placing particular emphasis on water scarcity and the resultant risks to livelihoods, food security and the environment. They evaluate the risks and reality of climate change in the region, and offer an assessment of the vulnerability of agriculture and livelihoods. In a final section, they explore the options for responding to the new challenges, including policy, institutional, economic and technical measures.

Agriculture played an important role in the transition to capitalism in the United States in the mid-nineteenth century. In her study, Sue Headlee argues that the family farm system, with its progressive nature and egalitarian class structure, revolutionized this transition to capitalism. The family farm is examined in light of its economic and political implications, showing the relationship between the family farm and fledgling industrial capitalism, a relationship that fostered the simultaneous industrial and agricultural revolutions and the creation of an agro-industrial complex. Headlee focuses on the adoption of the horse-drawn mechanical reaper (to harvest wheat) by family farmers in the 1850s. The neoclassical economic explanation, with its emphasis on the farm as a profit-maximizing firm, is criticized for its lack of recognition of the role of the family farM's egalitarian class structure. This look at the economic history of the United States has lessons for the Third World today: agricultural development is vital to the transition to capitalism; the agrarian class structures of Third World countries may be holding back that transition; and a family farm/land reform approach would lead to increases in productivity and in the material well-being of society.

Headlee's analysis supports three important debates in political economy, thus providing the historical and theoretical context for understanding the role of agriculture in the transition to capitalism in general and in the particular case of the United States. Her findings conclude that agrarian class structures can explain the differential patterns of development in pre-industrial Europe. Further evidence is presented that the internal class structure of agrarian society is the crucial causal factor in the transition to capitalism and that market developments alone are not sufficient. Lastly and most controversially, Headlee acknowledges the importance of the Civil War in propelling the triumph of American capitalism, allowing the Republican Party (an alliance of family farmers and industrial capitalists) to take control of the state from the Democratic Party of the southern plantation owners. This book will be of interest to scholars in political economy, economic history, agrarian economics, and development economics.

Micro irrigation techniques with diverse crops are discussed, including sweet pepper, chili, tomatoes, cauliflower, wheat, sweet peas, sugarcane, and potatoes. The performance of the various techniques has been tested and evaluated in the field. Written by experts on micro irrigation, this valuable book is a must-have for micro irrigation professionals as well as advanced students.

The reuse of wastewater in irrigation is being practiced only recently to solve water scarcity problems in agriculture. Management of water, soil, crop, and operational procedures, including precautions to protect farm workers, play an important role in the successful use of sewage effluent for irrigation. Appropriate water management practices must be followed to prevent salinization. If salt is not flushed out of the root zone by leaching and removed from the soil by effective drainage, salinity problems can build up rapidly. Leaching and drainage are, thus, two important water management practices to avoid salinization of soils. One of the options that may be available to farmers is the blending of treated sewage with conventional sources of water to obtain a blended water of acceptable salinity level. This important book focuses on the use of wastewater as a valuable resource for agricultural micro irrigation purposes. It covers effective wastewater management practices in a variety of climates, including semi-arid regions and others; how to perform effective evaluations to gauge the quality of the water on plants, including potatoes, maize, and eggplant; and the cost-benefit of using wastewater. It addresses the sources of wastewater for irrigation and the problems along with challenges, including water quality, clogging, soil quality, and more. The mission of this compendium is to serve as a reference manual for professionals in biological and civil engineering, horticulture, soil and crop science, and agronomy, as well as for graduate and undergraduate students in related fields. It will be a valuable reference for professionals who work with micro irrigation/wastewater and water management, for technical agricultural centers, irrigation centers, agricultural extension services, and other agencies that work with micro irrigation programs.

As for the preceding four International Symposia on Nitrogen Fixation, held in Pullman, Washington USA (1974); Salamanca, Spain (1976); Madison, Wisconsin, USA (1978); and Canberra, Australia (1980), the 5th Symposium held from August 28 - September 3, 1983 in Noordwijkerhout, The Netherlands, received the gene rous support of the Charles F. Kettering Foundation Research Laboratory and the Tennessee Valley Authority. This support has helped research progress in this broad field of science by offering a forum both for the exchange of ideas and for scientific summary and discussion as captured over the last 10 years in each of the four books published previously. Although all previous meetings were well attended, the present conference was the largest so far. 550 scien tists from 60 different countries attended the "Leeuwenhorst Conference", re presenting the many different disciplines actively involved in research in this field: chemists, biochemists, molecular biologists, geneticists, microbiologists, plant physiologists, agriculturalists. A large number of them had to go through a difficult period to raise the necessary funds to attend. In addition, a parallel meeting of "policymakers" from Southeast Asia, Africa and South America was held under the auspices of Crosscurrents International Institute, Dayton, OR, USA and the United Nations University, Tokyo, Japan. These participants attended some of the scientific sessions to benefit from the vision of a number of scientists at the symposium.

This book forms the proceedings of the 18th European conference on irrigation and drainage. Water is not a free commodity, and demand is becoming more and more intense for its allocation. This book focuses on the role of irrigation and drainage in the debate on water, and will be used by planners, designers and policy makers internationally.

One section of the book focuses on water management in the cultivation of sugarcane, a very important industrial crop used in many fields. Other sections are devoted to principles and challenging technologies, water use efficiency for drip-irrigated crops, performance of fertigated rice under micro irrigation, and evaluation of performance of drip-irrigated crops. This valuable book is a must for those struggling to find ways to address the need to maintain efficient crop production in the midst of water shortages. With chapters from hands-on experts in the field, the book will be an invaluable reference and guide to effective micro irrigation methods.

"In this timely publication, Dr Rott has sourced contributions from scientists working on cane throughout the tropics...Richly referenced, this is both an informed and informative book that is well written. It will appeal to both researchers and cane growers." International Sugar Journal/Agribusiness intelligence Sugarcane is the source of over three quarters of the world's sugar, and is grown widely in the tropics and sub-tropics. Despite rising demand, average yields have not increased significantly, partly because of continued vulnerability to pests and diseases. In addition, cultivation has been seen as damaging biodiversity and soil health with a negative effect on both yields and the environment. This volume summarises the wealth of research addressing these challenges. Volume 1 reviews cultivation techniques and sustainability issues. Part 1 summarises current best practice in sugarcane cultivation across the value chain, from planting through to post-harvest operations. Part 2 looks at ways of measuring the environmental impact of sugarcane cultivation as well as ways of supporting smallholders. With its distinguished editor and international team of expert authors, this will be a standard reference for sugarcane scientists, growers, government and non-governmental agencies responsible for supporting and monitoring the impact of sugarcane cultivation. It is accompanied by a companion volume reviewing breeding, pest and disease management.

An introduction to runoff agriculture - a form of agricultural irrigation - this text describes how the use of surface and subsurface water, often overlooked and wasted, enables both small farmers and commercial agriculturists to improve yields and the security of harvest, even in harsh and remote environments. The text introduces the techniques and strategies, as well as the challenges and the potential of the crucial approach, which can contribute so much to reducing land degradation and improving conservation and sustainability.

Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'. Most research on drip irrigation use plot-level studies to demonstrate the technology's ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation.

Micro irrigation, also known as trickle, drip, localized, high frequency, or pressurized irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant. Clogging is a menace in the success of drip irrigation systems, and the situation is more complex under subsurface drip irrigation. Irrigation planners and engineers have found a variety of innovative methods to help to minimize clogging. This book emphasizes the implications of micro irrigation clogging, especially under the subsurface placement of laterals. The book offers remedies to decrease clogging and methodologies to improve the performance of micro sprinklers. This valuable resource addresses this critical problem, covering: Challenges in clogging under subsurface drip irrigation Principles, practices, and management of emitter clogging Efficiency of acidification for unclogging of emitters Performance characteristics of micro sprinklers The book will serve as a reference manual for professionals in biological and civil engineering, horticulture, soil and crop science, and agronomy, as well as for graduate and undergraduate students in related fields. It will be a valuable reference for professionals who work with micro irrigation/wastewater and water management and for technical agricultural centers, irrigation centers, agricultural extension services, and other agencies that work with micro irrigation programs.

This new book, Sustainable Micro Irrigation Design Systems for Agricultural Crops, brings together the best research for efficient micro irrigation methods for field crops, focusing on design methods and best practices. Covering a multitude of topics, the book presents research and studies on: Indigenous alternatives for use of saline and alkali waters Hydraulic performance Distribution of moisture Fertigation technology Buried micro irrigation laterals Drip irrigation scheduling Rainwater harvesting Adoption and economic impact of a micro irrigation model This book is a must for those interested in irrigation planning and management, namely, researchers, scientists, educators, and students.

Closed circuit trickle irrigation is a form of micro irrigation that increases energy and water efficiency by using closed circuit drip irrigation systems designs. Modifications are made to traditional micro irrigation methods to reduce some of the problems and constraints, such as low compressor water at the end of irrigation lines. This approach has proved successful for the irrigation of fruit trees and some vegetable and field crops. Closed circuits of drip irrigation systems require about half of the water needed by sprinkler or surface irrigation. Lower operating pressures and flow rates result in reduced energy costs, and a higher degree of water control is attainable as well. Plants can be supplied with more precise amounts of water, and disease and insect damage is reduced because plant foliage stays dry. Fertilizers can also be applied through this type of system, which can result in a reduction of fertilizer and fertilizer costs. This new volume in the Research Advances in Sustainable Micro Irrigation book series presents a diverse collection of research on closed circuit irrigational technology and design and provides studies of its use on such crops as wheat, maize, yellow corn, soybeans, rice, and snap peas. The book explores: * Soil moisture and salinity distributions under modified sprinkler irrigation * Performance of sprinkler irrigation * Design considerations for closed circuit drip irrigation systems * Performance of bubbler irrigation * Energy and water savings of drip irrigation systems * Automation of mini-sprinkler and drip irrigation systems * Water and fertilizer use efficiencies for drip irrigated maize * Evaluation of emitter clogging for drip irrigated systems This book will be valuable for those interested in irrigation planning and management, namely, researchers, scientists, educators, upper-level students, agricultural extension services, and others.
