Hazardous and Trace Materials in Soil and Plants: Sources, Effects and Management explores the latest advancements in reducing, avoiding and eliminating soil contaminants that challenge the health and safety of agricultural plants. With a focus on minimizing the production of those hazardous substances, controlling their distribution and ensuring safe utilization, the book explores each contributing area and provides insights toward improved, sustainable and secure production. This is an excellent reference resource on both current research and future directions from laboratory research to field applications. The combined impacts of climate change and industrialization have led to increased and diversified threats to the health of the soil in which our food crops are grown, as well as in the plants themselves. This dual-hazard scenario is increasingly recognized as a threat to not just the environment, but to global food security as agricultural soils contaminated with pollutants alter plant metabolism, thus resulting in reduced crop quality and production quantity.

1.1. INTRODUCTION Plastic covering, either framed or floating, is now used worldwide to protect crops from unfavorable growing conditions, such as severe weather and insects and birds. Protected cultivation in the broad sense, including mulching, has been widely spread by the innovation of plastic films. Paper, straw, and glass were the main materials used before the era of plastics. Utilization of plastics in agriculture started in the developed countries and is now spreading to the developing countries. Early utilization of plastic was in cold regions, and plastic was mainly used for protection from the cold. Now plastic is used also for protection from wind, insects and diseases. The use of covering techniques started with a simple system such as mulching, then row covers and small tunnels were developed, and finally plastic houses. Floating mulch was an exception to this sequence: it was introduced rather recently, although it is a simple structure. New development of functional and inexpensive films triggered widespread use of floating mulch. Table 1.1. The use a/plastic mulch in the world (after Jouet, 2001).

The improvement of crop species has been a basic pursuit since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and few others are expected to lead as the most important crops in the world. Enormous efforts are made all over the world to document as well as use these resources. Everybody knows that the introgression of genes in wheat provided the foundation for the "Green Revolution". Later also demonstrated the great impact that genetic resources have on production. Several factors are contributing to high plant performance under different environmental conditions, therefore an effective and complementary use of all available technological tools and resources is needed to meet the challenge.

The rapidly growing human population has increased the dependence on fossil fuel based agrochemicals such as fertilizers and pesticides to produce the required agricultural and forestry products. This has exerted a great pressure on the non renewable fossil fuel resources, which cannot last indefinitely. Besides, indiscriminate use ofpesticides for pests (weeds, insects, nematodes, pathogens) control has resulted in serious ecological and environmental problems viz., (A) Increasing incidence of resistance in pest organisms to important pesticides. (B) Shift in pests population, particulary in weeds and insects. In weeds, species that are more closely related to the crops they infest have developed. In insects, scenario is most grim, the predators have been killed and minor insect pests have become major pests and require very heavy doses ofhighly toxic insecticides for their control. (C) Greater environmental pollution and health hazards (a) particularly from contamination of surface and underground drinking water resources and (b) from their inhalation during handling and application. (D) Toxic residues of pesticides pollute the environment and may prove hazardous to even our future generations. (E) Some agricultural commodities may contain minute quantities ofpesticides residues, with long tenn adverse effects on human and livestock health. Therefore, serious ecological questions about the reliance on pesticides for pests control has been raised. The use of fertilizers, besides causing environmental problems has also impoverished the soil health and decreased the beneficial soil fauna. For example, in some major crop rotations viz."

In recent years there has been an unprecedented expansion of knowledge about anthocyanins pigments. Indeed, the molecular genetic control of anthocyanins biosynthesis is now one of the best understood of all secondary metabolic pathways. There have also been substantial improvements in analytical technology that have led to the discovery of novel anthocyanin compounds. Armed with this knowledge and the tools for genetic engineering, plant breeders are now introducing vibrant new colors into horticultural crops. The food industry has also benefited from the resurgence of interest in anthocyanins. A greater understanding of the chemistry of these pigments has led to improved methods for stabilizing the color of anthocyanins extracts, so that they are more useful as food colorings. Methods for the bulk production of anthocyanins from cell cultures have been optimized for this purpose. Possible benefits to human health from the ingestion of anthocyanin-rich foods have also been a major feature of the recent scientific literature. Anthocyanins are remarkably potent antioxidants, and their ingestion has been postulated to stave off the effects of oxidative stress. These pigments, especially in conjunction with other flavonoids, have been associated with reductions in the incidence and severity of many other non-infectious diseases, including diabetes, cardiovascular disease and certain cancers. An industry is developing around anthocyanins as nutritional supplements. Finally, there has been significant progress in our understanding of the benefits of anthocyanins to plants themselves. Originally considered an extravagance without a purpose, anthocyanins are now implicated in multifarious vital functions. These include the attraction of pollinators and frugivores, aposematic defense from herbivores, and protection from environmental stressors such as strong light, UVB, drought, and free radical attacks. Anthocyanins are evidently highly versatile, and enormously useful to plants. This book covers all aspects of the biosynthesis and function of anthocyanins (and related compounds such as proanthocyanidins) in plants, and their applications in agriculture, food products, and human health. Featured areas include their relevance to: * Plant stress * Flower and fruit color * Human health * Wine quality and health attributes * Food colorants and ingredients * Cell culture production systems * The pastoral sector

Growing concerns about the impacts of climate change and dependence on fossil fuels have intensified interest in bioenergy from sugar cane and other crops, highlighting important links between energy, environment and development goals. Sub-Saharan Africa is characterized by severe poverty; the possibility to exploit a renewable energy resource offers valuable avenues for sustainable development and could support a more dynamic and competitive economy. This book describes how the bioenergy expansion will improve rural livelihoods, reduce costly energy imports, reduce GHG emissions, and offer new development paths.

Drawing on international experience, it is shown that harnessing this potential will require significant increases in investment, technology transfer, and international cooperation. Because of its high efficiency, the authors argue that sugar cane should be viewed as a global resource for sustainable development and should command much greater focus and concerted policy action. Through an analysis of the agronomy, land suitability and industrial processing of sugar cane and its co-products, along with an assessment of the energy, economic and environmental implications, this volume demonstrates that sugar cane offers a competitive and environmentally beneficial resource for Africa's economic development and energy security.

With fourty-four authors representing thirty organisations in sixteen countries, the book offers a truly international and interdisciplinary perspective by combining technical and economic principles with social, political and environmental assessment and policy analysis.

Genome Mapping and Molecular Breeding in Plants presents the current status of the elucidation and improvement of plant genomes of economic interest. The focus is on genetic and physical mapping, positioning, cloning, monitoring of desirable genes by molecular breeding and the most recent advances in genomics. The series comprises seven volumes: Cereals and Millets; Oilseeds; Pulses, Sugar and Tuber Crops; Fruits and Nuts; Vegetables; Technical Crops; and Forest Trees.

Technical Crops includes plants of great agricultural importance. One chapter is devoted to cotton, the most important fiber crop on which significant progress in molecular genetic research has been made. Reviews on oil palm, coffee, tea, cocoa and rubber describe traditional breeding and preliminary molecular results. Chapters on forage crops, ornamentals, and medicinal and aromatic plants each cover a large number of crops and may serve as road maps for further molecular research.

Presented by an international team of experts, this resource updates on the latest in synthesis, physical, chemical and optical properties, along with the effects and mechanisms of carbon dots, all further explained in real-world studies. Finally, the book highlights emerging innovative topics which are of great relevance to scientists, academicians and innovators in agriculture (soil science, agricultural chemistry and agronomy) and biotechnology for further research and development.

Phosphorus (P) is an essential macronutrient for plant growth. It is as phosphate that plants take up P from the soil solution. Since little phosphate is available to plants in most soils, plants have evolved a range of mechanisms to acquire and use P efficiently - including the development of symbiotic relationships that help them access sources of phosphorus beyond the plant's own range. At the same time, in agricultural systems, applications of inorganic phosphate fertilizers aimed at overcoming phosphate limitation are unsustainable and can cause pollution.

This latest volume in Springer's Plant Ecophysiology series takes an in-depth look at these diverse plant-phosphorus interactions in natural and agricultural environments, presenting a series of critical reviews on the current status of research. In particular, the book presents a wealth of information on the genetic and phenotypic variation in natural plant ecosystems adapted to low P availability, which could be of particular relevance to developing new crop varieties with enhanced abilities to grow under P-limiting conditions.

The book provides a valuable reference material for graduates and research scientists working in the field of plant-phosphorus interactions, as well as for those working in plant breeding and sustainable agricultural development.

While working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (1974-1976), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts. In numerous stimu lating discussions with Professor Reinert on this subject, I was fully convinced that somatic embryogenesis would become one of the most important areas of study, not only regarding basic and fundamental aspects, but also for its application in crop improvement. During the last decade, we have witnessed tremendous interest and achievements in the use of somatic embryos for the production of synthetic seeds, for micro propagation, genetic transformation, cryopreservation, and conservation of germplasm. The en masse production of somatic embryos in the bioreactors has facilitated some of these studies. Somatic embryos have now been induced in more than 300 plant species belonging to a wide range offamilies. It was therefore felt that a compilation ofliterature/state of the art on this subject was necessary. Thus, two volumes on Somatic Embryo genesis and Synthetic Seed have been compiled, which contain 65 chapters contributed by International experts. Somatic Embryogenesis and Synthetic Seed I comprises 31 chapters, arranged in 3 sections: Section I Commitment of the cell to somatic embryogenesis; early events; anatomy; molecular basis; gene expression; role of polyamines; machine vision analysis of somatic embryos. Section II Applications of somatic embryos; technology of synthetic seed; fluid drilling; micropropagation; genetic transfor mation through somatic embryos; cryopreservation.

This book contains papers and posters presented at the 18th Eucarpia Fodder Crops Section Meeting held at Loen, Nordfjord, Norway in August 1993. In most environments some form of marginal conditions or stress prevails. Few crops are being produced under such a wide range of environmental and management stresses as fodder crops. Improved adaptation of fodder crops to marginal conditions is crucial in developing sustainable, low-input agricultural systems. The book is unique in demonstrating the large diversity both in crops and environmental stresses that confront the forage breeders. Both general and specific aspects of adaptation to marginal growing conditions are presented, ranging from problems caused by snow and ice in the Subarctic regions of Europe to the severe drought problems in the Mediterranean regions. For everyone involved in studies of adaptation and breeding of perennial plants for marginal conditions or stress environments.

Plant Factory Basics, Applications, and Advances takes the reader from an overview of the need for and potential of plant factories with artificial lighting (PFALs) in enhancing food production and security to the latest advances and benefits of this agriculture environment. Edited by leading experts Toyoki Kozai, Genhua Niu, and Joseph Masabni, this book aims to provide a platform of PFAL technology and science, including ideas on its extensive business and social applications towards the next-generation PFALs. The book is presented in four parts: Introduction, Basics, Applications, and Advanced Research. Part 1 covers why PFALs are necessary for urban areas, how they can contribute to the United Nations' Sustainable Development Goals, and a definition of PFAL in relation to the term "indoor vertical farm." Part 2 presents SI units and radiometric, photometric, and photonmetric quantities, types, components, and performance of LED luminaires, hydroponics and aquaponics, and plant responses to the growing environment in PFALs. Part 3 describes the indexes and definition of various productivity aspects of PFAL, provides comparisons of the productivity of the past and the present operation of any given PFALs, and compares PFALs with one another from the productivity standpoint by applying the common indexes. Part 4 describes the advances in lighting and their effects on plant growth, breeding of indoor and outdoor crops, production of fruiting vegetables and head vegetables, and concluding with a focus on a human-centered perspective of urban agriculture. Providing real-world insights and experience, Plant Factory Basics, Applications, and Advances is the ideal resource for those seeking to take the next step in understanding and applying PFAL concepts.

Fantasies and dreams have their rightful place in science, and sometimes they turn into reality. Regeneration of hybrid plants through protoplast fusion is one such dream come true. In the early 1970s I shared the pioneering excitement in the field of protoplast technology at the Second International Congress of Plant Tissue Culture held in Strasbourg, France. Subsequently, I participated in three international conferences devoted to plant protoplasts, in Salamanca, Spain (1972), Versailles, France (1972), and Nottingham, England (1975). At Versailles Dr. P.S. Carlson presented his work on the successful regeneration of somatic hybrids between Nicotiana glauca and Nicotiana langsdorfii. The enthusi- asm shown by the participants was sufficient indication of the bright future of somatic hybridization. On my return from Versailles, I gathered my thoughts and prepared a concept paper on Potentials of Protoplast Culture Work in Agriculture which was published in Euphytica (Bajaj 1974). The studies on protoplast fusion and somatic hybridization then gained momentum and active work started in many laboratories. Very significant work was done by Melchers et al. (1978) who obtained a somatic hybrid between potato and tomato, calling it "Pomato".

Jatropha curcas or Physic Nut is a small tree (bush plant) that produces fruits under tropical climate. The fruits contained seed that are 40 percent oil rich. This oil is excellent for biodiesel. The bush is a now new coming crop because it may cope with harsh environmental conditions such as semi-aridity and poor land. It is considered as one alternative for climate mitigation that does not compete with arable land normally dedicated to food crop and can be used to regain degraded land or fight desertification. This bush has been considered seriously by the international community only recently (2006-2008), but worldwide scientists did an outstanding job to drawn Jatropha out of its semi-wild status and bring it on the industrial scene. Problems remains, but we have now a comprehensive picture of this crop and almost every technological challenged were addressed. From now, the job will have to concentrate on breeding in order to domesticate this species. Therefore, it is the right time to sum up worldwide contributions in a comprehensive book with a breeding looking to improve the chance of this plant to stabilize as a crop and to fulfil with the expectations that humans invested in it. A book with this perspective will help international community to give a step on. The book will be a broad and comprehensive look on Jatropha until the details since the book is being contributed by international experts worldwide that have already published works in the international press of Science. Illustrations, tables geographic maps, GPS location, etc are added by each contributors according to the feeling they have concerning what they think their contribution should be.

Crops experience an assortment of environmental stresses which include abiotic viz., drought, water logging, salinity, extremes of temperature, high variability in radiation, subtle but perceptible changes in atmospheric gases and biotic viz., insects, birds, pests, weeds, pathogens (viruses and other microbes). The ability to tolerate or adapt and over winter by effectively countering these stresses is a very multifaceted phenomenon. In addition, the inability to do so which renders the crops susceptible is again the result of various exogenous and endogenous interaction in the ecosystem. Both biotic and abiotic stresses occur at various stages of plant development and frequently more than one stress concurrently affects the crop. Stresses result in both universal and definite effects on plant growth and development. One of the imposing tasks for the crop researchers globally is to distinguish and to diminish effects of these stress factors on the performance of crop plants, especially with respect to yield and quality of harvested products. This is of special significance in view of the impending climate change, with complex consequences for economically profitable and ecologically and environmentally sound global agriculture. The challenge at the hands of the crop scientist in such a scenario is to promote a competitive and multifunctional agriculture, leading to the production of highly nourishing, healthy and secure food and animal feed as well as raw materials for a wide variety of industrial applications. In order to successfully meet this challenge researchers have to understand the various aspects of these stresses in view of the current development from molecules to ecosystems. The book will focus on the following broad research areas in relation to these stresses which are in the forefront in contemporary crop stress research.

This book, first published in 1990 and reprinted here, is a comprehensive, state-of-the art reference on the design principles and management techniques of two primary agricultural irrigation methods. The book presents a systematic approach to the optimal design, management and operation of these two systems. Focusing on the synthesis of the entire design process, the authors present the chapters in the sequence used to design systems with the analytical material presented and demonstrated in a concise manner. For the first time in any book, Sprinkle and Trickle Irrigation offers complete design strategies and presentations for all of the major types of sprinkle and trickle systems: - Periodic-move - Center-pivot - Traveling sprinkler - Linear-moving - Set sprinkler - Drip, spray and line-source Sequential sample calculations that involve the steps in the design of typical irrigation systems are used extensively. As the book progresses, these calculations become more comprehensive and are linked together to form complete design packages for the various types of pressurized systems. The book also presents a section on selecting pressurized irrigation systems, a review of soil-plant-water relationships, unique insight into pipeline hydraulics and economics, design specifications for fertilization and frost control, a glossary and an annotated bibliography of ASAE Standards for Pressurized Irrigation Systems. Sprinkle and Trickle Irrigation is an important practical reference for agricultural engineers, irrigation system designers and agricultural managers, as well as a vital text for professors and researchers in agricultural engineering. "Sprinkle and Trickle Irrigation presents beginning-to-end coverage of the processes and computations needed in the planning and design of sprinkle and trickle irrigation systems. The textbook is created for the thinking person who desires more than cookie-cutter recipes or simple, routine "rule-of-thumb" designs. Rather, the authors of Sprinkle and Trickle Irrigation present concise rationale and philosophy behind each computation formula, figure and table. They decouple "recommended" design parameters into underlying components that can be recoupled at the time of the design to apply to specific cases and situations. In the process, the reader gains visualization skills that allow him/her to peer "inside" an irrigation system, both hydraulically, economically, and operationally. Sprinkle and Trickle Irrigation is a classic design text and reference that should be on every practitioner's desk. The chapters on center-pivot, linear-move and travelling sprinklers go well beyond other current texts. Solid and encompassing economics are infused into all design topics, including application, distribution, and pumping systems. I have lectured out of Sprinkle and Trickle Irrigation for twelve years at the university-senior level. I am confident that all students who completed this design course know not only how to design efficient and effective pressurized irrigation systems, but also know why they use the procedures that they use."
