Book Description
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.

Book Description
Forages: The Science of Grassland Agriculture, 7th Edition, Volume II will extensively evaluate the current knowledge and information on forage agriculture. Chapters written by leading researchers and authorities in grassland agriculture are aggregated under section themes, each one representing a major topic within grassland science and agriculture. This 7th edition will include two new additional chapters covering all aspects of forage physiology in three separate chapters, instead of one in previous editions. Chapters will be updated throughout to include new information that has developed since the last edition. This new edition of the classic reference serves as a comprehensive supplement to An Introduction to Grassland Agriculture, Volume I.

Book Description
Food quality is becoming an ever-increasing important feature for consumers and it is well known that some food crops are perishable and have a very short shelf and storage life. An effective quality assurance system throughout the handling steps between harvest and retail display is essential to provide a consistently good quality supply of fresh food crops to the consumers and to protect the reputation of a given marketing label. Food manufacturing companies all over the world are incre- ingly focussing on quality aspect of food including minimally processed food to meet consumer demands for fresh-like and healthy food products. To investigate and control quality, one must be able to measure quality-related attributes. Quality of produce encompasses sensory attributes, nutritive values, chemical constituents, mechanical properties, functional properties and defects. Successful postharvest handling of crops requires careful coordination and integration of the various steps from harvest operations to consumer level in order to maintain the initial product quality. Maturity at harvest is one feature of quality of perishable products, it has great influence on their postharvest behavior during marketing. Safety assurance can be part of quality assurance and its focus on minimizing chemical and microbial contamination during production, harvesting, and postharvest handling of intact and fresh-cut of commodities. Essentially, electromagnetic (often optical) prop- ties relate to appearance, mechanical properties to texture, and chemical properties to flavor (taste and aroma).

Book Description
This new volume looks at new research and advances in the use of nanotechnology applications in agricultural and bioprocess engineering. The first section deals with the impact of nanotechnology in agricultural engineering, looking at the role of nanomaterials in plant growth and nutrition. It goes on to discuss specific methods and processes in the development of food products, nutraceuticals, and therapeutics. This includes nanotechnological methods for iron fortification of dairy food, for processing and preservation of meat and meat products, for selective targeting of cancer, and more. The book then discusses the role of nanotechnology in bioprocessing, such as for biofuel production, for wastewater treatment, and as enzymatic nanoparticles for fabrication processes.

Book Description
From Mediterranean Europe to Chile and from China to Australia, chestnut cultivation surface has greatly increased globally over the last several decades. The crop provides solid revenue to growers, is resilient to climate change and the fruits are a calorie-dense, carbohydrate-rich nut, the production of which improves soil and sequesters carbon. However, there is a great lack and a great need for technical information on management of old and new chestnut plantations. The Chestnut Handbook shares achievements in chestnut development and cultivation including information on sustainable planning and management of chestnut production from nursery to plantation, entomology, pathology, and ecosystem services. Cultivation techniques of Chinese, Japanese, and European chestnut species including hybrids are described containing information on over 550 local and commercial cultivars. Beautiful original handmade drawings and technical sheets facilitate accessibility and comprehension of information. FEATURES: • Offers practical, easy-to-follow, technical solutions for chestnut farming and forestry, provides ideas for present and future plantations and management • Contains more than 300 figures published in full color featuring original handmade drawings • Provides information about cultural practices, nursery techniques and ecosystem services • Includes a reference list of over 550 local and commercial cultivars of Chinese, Japanese, and European chestnut species and their hybrids • Presents important information on both major and minor pests and diseases as well as pest diseases and physiological disorders. With the collaboration of more than 30 researchers from internationally renowned institutes, professionals and nurserymen this book serves as a technical reference and valuable resource for agronomists, forest experts, farmers, researchers and students of agricultural and forestry sciences.

Book Description
Here is a comprehensive summary of new research and advancements in the unique functional and nutraceutical therapeutic and physiochemical aspects of dairy foods. The book explores the specific health benefits of dairy ingredients in nutraceuticals and functional foods as well as delves into production techniques that enhancement their therapeutic value. The first section of the book looks at the physicochemical and technological aspects of milk-derived components, discussing production, extraction and purification, and functional and technological applications of various functional dairy ingredients (such as lactulose, casein and whey protein-derived bioactive peptides). The volume also considers the therapeutic aspects of dairy ingredients, detailing the physiological and health effects of colostrum, oligosaccharides, conjugated linoleic acid, and lactoferrin. The third section focuses on enhancing the functionality of dairy foods by assessing the functional attributes that can be augmented by the addition of nutraceuticals such as probiotics, vitamins, and minerals or by the removal of cholesterol. Functional Dairy Ingredients and Nutraceuticals: Physicochemical, Technological, and Therapeutic Aspects provides an abundance of important research on the use of dairy ingredients in functional foods and nutraceuticals that will be valued by researchers, scientists, students, growers, traders, processors, industries, and others involved with the physicochemical, technological and therapeutic aspects of various nutraceuticals and functional dairy ingredients and their application in food and dairy industry.
