Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.

This is a hands-on, practical guide to describe physical bunch and oil analysis of oil palm. Bunch and oil analysis laboratories are set up at oil mills to assess production, yield potential of plantations and oil extraction rates relative to targets. The higher the oil yields produced by the planting material, the less land that is needed to achieve a specific level of production, hence helping in the sustainability of the crop. Practical, illustrated steps are given in determining bunch and oil characteristics of oil palm. Promoting green, eco-friendly agriculture, this book covers: An introduction to bunch and oil analysis Health and safety considerations Bunch sampling Physical bunch analysis of stalks, spikelets, fruits and nuts Fruit sampling Nut analysis and measurements of components Oil analysis, oil extraction and measurement Calculation of bunch components and reporting. This is an invaluable manual for oil palm mill managers, oil palm plantation managers, palm oil producers, oil palm breeders, agronomists, oil chemists, oil palm seed producing companies and research institutes across the world (especially tropical zones). It is useful for those starting a career in oil palm production, as a reference guide for managers and for training purposes.

As such, scientists are developing stress-tolerant cultivars using agronomic, genetic and molecular approaches. Gathering papers on these developments, this timely book is a valuable resource for a wide audience, including plant scientists, agronomists, soil scientists, botanists, environmental scientists and extention workers.

"My earliest recollection of Colkirk was, I think, the Diamond Jubilee of good Queen Victoria in 1897 ... " Alfred Absolon's memoir is a unique window into life in rural Norfolk before the Great War and a story full of his family's farming heritage. He grows up on his aunt's farm in the village of Colkirk. This is a place where folklore is as real as the seasons and the harvest is gathered by men and horses. The threshing machine is powered by a steam engine, and the village is home to traditional craftsmen who practice a fading way of life. This is an authentic and unforgettable first-person account of life in a Norfolk village at the turn of the century (1897-1929)

Tobacco is one of the most economically important agricultural crops in the world. Indeed, farmers in over 100 developed and developing nations rely upon tobacco production to provide a stable source of cash income, and the processing, manufacture, and distribution of tobacco products provide employment for thousands of other people throughout the globe. To support the development of this industry, scientific and technical questions have been addressed by numerous investigators and their research results have been disseminated in various journals and proceedings appropriate for their fields of study. This monograph is intended to be a compilation of research topics and address all segments of the tobacco industry - from seed to smoke.

Among the topics covered herein are the interrelationship among the growth and culture of the tobacco plant, the harvested leaves, their curing, processing and manufacture and the properties of the final product. The advancements in the genetics of tobacco and the future of biotechnological applications to tobacco improvement are addressed in terms of their impact on production and utilization. Tobacco is an inclusive term for number of different types of tobacco that require varied production and curing practices to deliver the characteristics unique for each tobacco type. These practices are described on a practical basis and analysed for their impact on leaf chemical and physical properties. Disease and insect control and management strategies are described within the context of good agricultural practices and this topic is extended to include control of insects in the stored product. A comprehensive update on tobacco would be incomplete withoutaddressing leaf marketing systems, processing, and the manufacture and design of cigarettes. Sections on these topics are followed by a wide-ranging review of our current knowledge of smoke chemistry.

Some of the world's most distinguished experts have contributed to this book, providing a broad and often in-depth look at scientific and technical issues related to the tobacco industry. Many authors highlight future challenges to the industry, and it is these challenges presented that will prove invaluable to all those involved in the tobacco industry. Together, these contributions comprise the most comprehensive reference work yet published on this crop.

Less than two decades ago, the world was focusing on the impending food crisis across Asia, which was given little hope of ever being able to meet its rapidly growing food demand. Since then, Asia has made a quantum leap in food production. Technological innovations and policies that promoted intensive rice production systems helped achieve this. The authors of this book argue that there is a growing sense of complacency about future food supplies in Asia and that such complacency is not warranted. While rice productivity may increase, this will be limited by a number of factors: withdrawal of land and labor from agriculture to other uses, increased competition for resources, and land degradation. It is unlikely to match the increase in demand for rice because of population growth. The book provides a thorough assessment of the opportunities for increasing land productivity, including crop diversification. It evaluates the successes and limitations of the Green Revolution for rice in Asia and projects economic and technological trends forward over the next three decades.

This book describes the current state of international grape genomics, with a focus on the latest findings, tools and strategies employed in genome sequencing and analysis, and genetic mapping of important agronomic traits. It also discusses how these are having a direct impact on outcomes for grape breeders and the international grape research community. While V. vinifera is a model species, it is not always appreciated that its cultivation usually requires the use of other Vitis species as rootstocks. The book discusses genetic diversity within the Vitis genus, the available genetic resources for breeding, and the available genomic resources for other Vitis species. Grapes (Vitis vinifera spp. vinifera) have been a source of food and wine since their domestication from their wild progenitor (Vitis vinifera ssp. sylvestris) around 8,000 years ago, and they are now the world's most valuable horticultural crop. In addition to being economically important, V. vinifera is also a model organism for the study of perennial fruit crops for two reasons: Firstly, its ability to be transformed and micropropagated via somatic embryogenesis, and secondly its relatively small genome size of 500 Mb. The economic importance of grapes made V. vinifera an obvious early candidate for genomic sequencing, and accordingly, two draft genomes were reported in 2007. Remarkably, these were the first genomes of any fruiting crop to be sequenced and only the fourth for flowering plants. Although riddled with gaps and potentially omitting large regions of repetitive sequences, the two genomes have provided valuable insights into grape genomes. Cited in over 2,000 articles, the genome has served as a reference in more than 3,000 genome-wide transcriptional analyses. Further, recent advances in DNA sequencing and bioinformatics are enabling the assembly of reference-grade genome references for more grape genotypes revealing the exceptional extent of structural variation in the species.

Agronomic crops have been used to provide foods, beverages, fodders, fuels, medicines and industrial raw materials since the dawn of human civilization. Today, agronomic crops are being cultivated by employing scientific methods instead of traditional methods. However, in the current era of climate change, agronomic crops are subjected to various environmental stresses, which results in substantial yield loss. To meet the food demands of the ever-increasing global population, new technologies and management practices are being adopted to boost yield and maintain productivity under both normal and adverse conditions. Scientists are now exploring a variety of approaches to the sustainable production of agronomic crops, including varietal development, soil management, nutrient and water management, pest management, etc. Researchers have also made remarkable progress in developing stress tolerance in crops through different approaches. However, achieving optimal production to meet the increasing food demand is an open challenge. Although there have been numerous publications on the above-mentioned problems, and despite the extensive research being conducted on them, there is hardly any comprehensive book available. In response, this book offers a timely resource, addressing all aspects of production technologies, management practices and stress tolerance in agronomic crops in a single volume.

Volatile (essential) oil crops yield a wide range of products - fresh and dried herbs, oils and oil components and various oleoresins. Changing lifestyles in developed countries have led to dramatic increases in demand for these products, particularly over the last decade. More varied use has been made of oils and herbs in cooking, and oil components are now being regarded as safe alternatives to synthetic food additives and crop protection substances.

The surge in demand for these produces has encouraged a number of temperate and mediterranean countries to evaluate a range of volatile oil-bearing species as alternative crops. This has resulted in a rapid expansion in the scientific and technical literature on culinary and medicinal herbs.

"Volatile Oil Crops" draws much of this literature together for the first time. It reviews the basic botany, physiology and biochemistry of the major species and then analyses the genetics of oil composition. The effects of oils on a wide range of organisms are discussed and the book surveys the biotechnological methods which can be employed in the laboratory production of oils. It concludes with a full analysis of the world trade in the products of volatile oils.

The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.

This book presents recent advances in global wheat crop research, including the effects of abiotic stresses like high and low temperatures, drought, hypoxia, salinity, heavy metals, nutrient deficiency, and toxicity on wheat production. It also highlights various approaches to alleviate the damaging effects of abiotic stress on wheat as well as advanced approaches to develop abiotic-stress-tolerant wheat crops. Wheat is probably one of the world's most important cereals; it is a staple food in more than 40 countries, and because of its adaptability is cultivated in almost every region. Global wheat production has more than doubled in the last 50 years due to higher yields. However, despite their high yield potential, modern wheat cultivars are often subject to crop loss due to the abiotic stresses. As such, plant breeders have long aimed to improve tolerance in order to maintain yield. Written by 85 experts, and offering the latest insights into wheat responses and tolerance to various abiotic stresses, it is a valuable tool for agronomists, plant breeders, plant physiologists and students in the field of plant science and agriculture. It is the first book to comprehensively cover past and current abiotic stress problems and tolerance mechanisms.

This volume continues the retrospective analyses of Volumes I and II, but goes beyond that in an attempt to understand how phenolic acids are partitioned in seedling-solution and seedling-microbe-soil-sand culture systems and how phenolic acid effects on seedlings may be related to the actual and/or conditional physicochemical properties (e.g., solubility, hydrophobicity, pKa, molecular structure and soil sorption/desorption) of simple phenolic acids. Specifically, it explores the quantitative partitioning (i.e., source-sink relationships) of benzoic and cinnamic acids in cucumber seedling-solution and cucumber seedling-microbe-soil-sand systems and how that partitioning may influence phenolic acid effects on cucumber seedlings. Regressions, correlations and conceptual and hypothetical models are used to achieve these objectives. Cucumber seedlings are used as a surrogate for phenolic acid sensitive herbaceous dicotyledonous weed seedlings. This volume was written specifically for researchers and their students interested in understanding how a range of simple phenolic acids and potentially other putative allelopathic compounds released from living plants and their litter and residues may modify soil chemistry, soil and rhizosphere microbial biology, seedling physiology and seedling growth. In addition, this volume describes the potential relationships, where they may exist, for direct transfer of organic compounds between plants, plant communication and plant-plant allelopathic interactions and addresses the following questions: Can physicochemical properties of phenolic acids be used as tools to help understand the complex behavior of phenolic acids and the ultimate effects of phenolic acids on sensitive seedlings? What insights do laboratory bioassays and the conceptual and hypothetical models of laboratory systems provide us concerning the potential behavior and effects of phenolic acids in field systems? What potential role may phenolic acids play in broadleaf-weed seedling emergence in wheat debris cover crop no-till systems?

The two closely related species of Potato Cyst-Nematodes (PCN), Globodera rostochiensis (Woll) and Globodera pallida Stone have a worldwide distribution. Both are internationally recognized plant quarantine organisms of actual or potential major economic importance wherever potatoes are grown or traded. They occur in large soil masses and also adhere to potato tubers as microscopic cysts, which represent a complex of morphologically identical, but behaviourally different virulence groups, or pathotypes. This presents major problems for their detection, identification and management. This book is a synthesis of current practical knowledge and underpinning scientific research on PCN globally. It is arranged in five sections, comprising nineteen chapters by leading practitioners and research nematologists, in which the biology, detection, identification and control options (including plant resistance) for PCN are examined. In addition, its worldwide status is considered, including South America, where PCN co-evolved with its potato host. Essential information is provided for professionals and advanced students of plant nematology and crop protection.

This book is essential reading for degree and postgraduate students of plant science, agronomy and animal production. Additionally, students and researchers in ecology and environmental science will also find it a valuable resource. The management sections will be of particular value to grassland advisers, consultants and progressive land users.

The grasses and legumes grown in pastures and rangelands form the basis of the worldwide animal production industry. Some species also have a significant role in the sport and leisure industry, for playing surfaces such as golf courses and football fields. It is therefore vitally important to ensure that seed supplies of appropriate species are available for use on a commercial scale. This book is published in association with the International Herbage Seed Production Research Group. It brings together leading researchers and along with its companion volume Forage Seed Production Volume 2: Tropical and Subtropical Species (to be published in late 1998), provides the definitive resource for all those concerned with breeding and profitable seed production for grasses and legumes used within grazing systems or recreation and amenity provision. The book is in two parts. Part 1 covers all aspects relevant to seed production, including improving seed yield and quality, crop management, harvesting, processing and the international seed trade. Part 2 consists of eleven case studies from eight countries covering three continents. This book and its companion should be read by all seed scientists involved in the breeding and commercial production of grass and legume seed. They also represent a valuable asset for all commercial seed suppliers. Additionally, the information presented within the book is important for all students and lecturers within departments of agriculture and plant breeding.

Maintaining soil health is fundamental to successful crop production and ecosystem sustainability. To enable effective management soil health must first be measured and then monitored and so the authors review and evaluate how soil organisms can be used to fulfil this role. This book is essential for all soil scientists and consultants. It is of particular relevance to those involved in soil health monitoring and maintenance as well as those undertaking soil remediation. It is also important reading for agronomists, ecologists and environmentalists. This book is a comprehensive and effective resource for all those working to sustain healthy soils.

Plant Adaptation and Crop Improvement focuses on the opportunities for increasing the efficiency of crop improvement by understanding the basis of variation for plant adaptation in agricultural production systems. Crop improvement strategies based on combinations of the statistical modelling methodologies used by plant breeders and the crop modelling methodologies used by crop physiologists/agronomists are developed and discussed. The book captures much of the experience of scientists from around the world who have worked on the challenging problem of achieving crop improvement in variable crop production systems. It represents a major synthesis for workers in plant breeding, crop physiology and agronomy.

Soybean is one of the world s leading sources of seed oil and seed protein and is grown extensively, particularly in the Americas and Asia. Indeed, soybean is the lowest-cost producer of vegetable oil, since the oil is a coproduct of its protein-rich meal. Major advances have recently been made in our understanding of soybean genetics and of the application of new technologies to soybean improvement. Thus it is now possible, using molecular methods, to alter the protein and oil composition of soybean, as well as produce other foreign proteins in the plant. Further progress should permit the improvement of nitrogen fixation and other desirable traits. This book focuses on recent progress in our understanding of the genetics and molecular biology of soybean and provides a broad review of the subject, from genome diversity to transformation and integration of desired genes using current technologies. It is aimed at workers in legume agronomy, plant genetics, breeding and biotechnology."

This book provides a comprehensive overview of grassland nitrogen incorporating information from crop science, soils and fertilizers, ruminant consumption and environmental aspects. The published information is reviewed on the various transformations of nitrogen in temperate grassland systems. These include those taking place in soils. The effects of soil, weather and management practices are discussed and considerable emphasis is placed on soil-plant-animal interactions. A second aim of the book is to describe the factors that influence the response of grassland to the application of fertilizer nitrogen, and how the optimum rate of application may be determined. In addition, nitrogen balances are described for different grassland systems, showing how the annual inputs and outputs vary greatly depending on sward type and management. The book is of interest to a wide readership, especially those engaged in research, teaching and advisory work, and students taking courses in agricultural and environmental sciences.

Just five years ago, it was generally believed that the number of food insecure people in the world was on continuous decline. Unfortunately, widespread soil degradation along with resistance to recommended agronomic practices, and little attempt to restore degraded soils have conspired with significant droughts (in regions that could least tolerate them) to swell the ranks of the food insecure to over a billion people. The U.N. Millennium Development Goals intent to halve hunger by 2015 will not be realized.
Food Security and Soil Quality brings together leading experts from across the world to provide a concise and factually supported exploration of the problem at hand and the critical steps needed to reverse it. Edited by Rattan Lal, and B.A. Stewart, two of the world s most respected soil scientists, this important work

• Assesses farming systems and food security in Sub-Saharan Africa, with special emphasis on land degradation
• Examines concerns with and approaches to soil quality management in Brazil and China
• Details achievable methods for improving soil quality for sustainable production
• Provides an insightful comparison of temporal changes in agricultural systems productivity in Punjab, India and Ohio
• Discusses the human dimension of the crisis including the influence of culture and spiritual beliefs

Dr. Lal himself writes that despite the existence of scientific data on sustainable management of soil and water resources, problems of soil and environmental degradation have persisted and have been aggravated. And that these problems are rooted in land misuse and soil mismanagement.
This book does provide policymakers and others with an understanding of the depth, complexity, and immediacy of this crisis, but more than a call to action, it also offers soil scientists working in this area with an understanding of what is being done and what needs to be done. Most importantly, this book helps us understand that the situation is not beyond remediation were we to act with great resolve and a sense of urgency.

A tree's leaves may be ever so good,
So may its bark, so may its wood;
But unless you put the right thing to its root,
It never will show much flower or fruit.
