This book was released on 2007-05-08 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants require nutrients in order to grow, develop and complete their life cycle. Mineral fertilizers, and hence the fertilizer industry, constitute one of the most imp- tant keys to the world food supplies. There is growing concern about the safety and quality of food. Carbon, hydrogen and oxygen, which, together with nitrogen, form the structural matter in plants, are freely available from air and water. Nitrogen, phosphorus and potassium, on the other hand, may not be present in quantities or forms sufficient to support plant growth. In this case, the absence of these nut- ents constitutes a limiting factor. The supply of nutrients to the plants should be balanced in order to maximise the efficiency of the individual nutrients so that these meet the needs of the particular crop and soil type. For example, it should be noted that EU-wide regulations are not designed to govern the specific details of mineral fertilizer use. Although plants receive a natural supply of nitrogen, phosphorus and potassium from organic matter and soil minerals, this is not usually sufficient to satisfy the demands of crop plants. The supply of nutrients must therefore be supplemented with fertilizers, both to meet the requirements of crops during periods of plant growth and to replenish soil reserves after the crop has been harvested. Pesticides are important in modern farming and will remain indispensable for the foreseeable future.

This book was released on 2019-12-05 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2019 Extra Joint FAO/WHO Meeting on Pesticide Residues (JMPR) was held in Gatineau/Ottawa, Canada from 7 to 17 May. The FAO and WHO Joint Meeting on Pesticide Residues (JMPR) is an expert ad hoc body administered jointly by FAO and WHO in the purpose of harmonizing the requirement and the risk assessment on the pesticide residues. The JMPR meets annually to evaluate possible hazards to humans arising from the occurrence of pesticide residues in foods. The Evaluation monographs of pesticide residues in food 2019-Part I (e-version only) includes summary of the residue data considered by the 2019 JMPR. The JMPR is the only scientific advisory body to service the Codex and FAO member countries in risk assessment of pesticide residues and in establishment of Codex MRL in food and feed. The JMPR report and evaluations are the unique technical publications in the review of pesticide residue data from around the world. The Report provides the evaluations of the Joint Meeting of the FAO Panel of Experts on Pesticide Residues in Food and the Environment and the WHO Core Assessment Group on Pesticide Residues. The extra Meeting evaluated 19 pesticides, including eight new compounds and three compounds that were re-evaluated for toxicity or residues, or both, within the periodic review programme of the Codex Committee on Pesticide Residues (CCPR).

Download or read book Plant Respiration Metabolic Fluxes and Carbon Balance written by Guillaume Tcherkez and published by Springer. This book was released on 2018-02-20 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are currently intense efforts devoted to understand plant respiration (from genes toecosystems) and its regulatory mechanisms; this is because respiratory CO2 productionrepresents a substantial carbon loss in crops and in natural ecosystems. Thus, in addition tomanipulating photosynthesis to increase plant biomass production, minimization ofrespiratory loss should be considered in plant science and engineering. However, respiratorymetabolic pathways are at the heart of energy and carbon skeleton production and therefore, itis an essential component of carbon metabolism sustaining key processes such asphotosynthesis. The overall goal of this book is to provide an insight in such interactions aswell as an up-to-date view on respiratory metabolism, taking advantage of recent advancesand concepts, from fluxomics to natural isotopic signal of plant CO2 efflux. It is thus a nonoverlapping,complement to Volume 18 in this series (Plant Respiration From Cell toEcosystem) which mostly deals with mitochondrial electron fluxes and plant-scale respiratorylosses.
Download or read book Fungal Ecology written by Neville J. Dix and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungi play vital roles in all ecosystems, as decomposers, symbionts of animals and plants and as parasites. Thus their ecology is of great interest. It has been estimated that there may be as many as 1. 5 million species of fungi, many of which are still undescribed. These interact in various ways with their hosts, with their substrates, with their competitors (including other fungi) and with abiotic variables of their environment. They show great variation in morphology, reproduction, life cycles and modes of dispersal. They grow in almost every conceivable habitat where organic carbon is available: on rock surfaces, in soil, the sea and in fresh water, at extremes of high and low temperature, on dry substrata and in concen trated solutions. Fungal ecology is therefore an enormous subject and its literature is voluminous. In view of this we have had to be selective in the material we have included in this book. We have chosen to concentrate on subjects in which we have some personal experience through either research or teaching. We preferred to tackle a few subjects in depth instead of attempting to cover a wider range of topics superficially. We are conscious of the extensive gaps in coverage: for example on the ecology of lichens, of fungal plant pathogens and of the complex interactions between fungi and animals. It is some justification that book-length treatments of these subjects are available elsewhere.

Download or read book Methods of Analysis of Food Components and Additives Second Edition written by Semih Otles and published by CRC Press. This book was released on 2011-11-16 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: With diet, health, and food safety news making headlines on a regular basis, the ability to separate, identify, and analyze the nutrients, additives, and toxicological compounds found in food and food components is more important than ever. This requires proper training in the application of best methods, as well as efforts to improve existing methods to meet analytical needs. Advances in instrumentation and applied instrumental analysis methods have allowed scientists concerned with food and beverage quality, labeling, compliance, and safety to meet these ever-increasing analytical demands. This updated edition of Methods of Analysis of Food Components and Additives covers recent advances as well as established methods in a concise guide, presenting detailed explanations of techniques for analysis of food components and additives. Written by leading scientists, many of whom personally developed or refined the techniques, this reference focuses primarily on methods of food analysis and novel analysis instruments. It provides readers with a survey of modern analytical instruments and methods for the analysis of food components, additives, and contaminants. Each chapter summarizes key findings on novel analysis methods, including the identification, speciation, and determination of components in raw materials and food products. The text describes the component or additive that can be analyzed, explains how it works, and then offers examples of applications. This reference covers selection of techniques, statistical assessments, analysis of drinking water, and rapid microbiological techniques. It also describes the application of chemical, physical, microbiological, sensorial, and instrumental novel analysis to food components and additives, including proteins, peptides, lipids, vitamins, carotenoids, chlorophylls, and food allergens, as well as genetically modified components, pesticide residues, pollutants, chemical preservatives, and radioactive components in foods. The Second Edition contains three valuable new chapters on analytical quality assurance, the analysis of carbohydrates, and natural toxins in foods, along with updates in the remaining chapters, numerous examples, and many new figures.
