Organic farming is not only a philosophy; it is also a well-researched science. The second edition of The Science and Technology of Organic Farming presents the scientific basis of organic farming and the methods of application needed to achieve adequate yields through plant nutrition and protection.Organic farming is a scientifically derived method of improving soil fertility to increase agricultural yields with limited chemical inputs. As such, it can meet public demand for reduced chemical inputs in agriculture and play a key role in meeting the needs of a growing world population. The new edition of this highly regarded book gives clear and comprehensive details on how soil fertility can be maintained and how plants can be nourished in organic agriculture.Chapters on soil fertility and plant nutrition explain the chemistry of the plant, the soil, and the soil solution and outline the importance of plant macronutrients and micronutrients.The book offers practical information on using of green manures, composts and lime to maintain soil fertility; introduces methods of tillage of land; provides organic methods of controlling weeds, insects, and diseases; and suggests how food produce can be stored without refrigeration.The text provides information on how to assess and govern the nutritional status of crops and the fertility and condition of soil and presents guidelines, recommendations, and procedures for determining the best fertility recommendations for individual situations.This edition includes an entirely new chapter on hydroponics that explains organic approaches to hydroponic crop production.With a full bibliography of references, this text is a practical guide for anyone interested in organic farming, from farmers and agricultural advisers to teachers, soil scientists, plant scientist, entomologists and students of other biological and environmental sciences.

In 2007, the first edition of Handbook of Plant Nutrition presented a compendium of information on the mineral nutrition of plants available at that time—and became a bestseller and trusted resource. Updated to reflect recent advances in knowledge of plant nutrition, the second edition continues this tradition. With chapters written by a new team of experts, each element is covered in a different manner, providing a fresh look and new understanding of the material. The chapters extensively explore the relationship between plant genetics and the accumulation and use of nutrients by plants, adding to the coverage available in the first edition. The second edition features a chapter on lanthanides, which have gained importance in plant nutrition since the publication of the first edition, and contains chapters on the different mineral elements. It follows the general pattern of a description of the determination of essentiality or beneficial effects of the element, uptake and assimilation, physiological responses of plants to the element, genetics of its acquisition by plants, concentrations of the element and its derivatives and metabolites in plants, interaction of the element with uptake of other elements, diagnosis of concentrations of the element in plants, forms and concentrations of the element in soils and its availability to plants, soil tests and fertilizers used to supply the element. The book demonstrates how the appearance and composition of plants can be used to assess nutritional status and the value of soil tests for assessing nutrition status. It also includes recommendations of fertilizers that can be applied to remedy nutritional deficiencies. These features and more make Handbook of Plant Nutrition, Second Edition a practical, easy-to-use reference for determining, monitoring, and improving the nutritional profiles of plants worldwide.
