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.

The aim of this book is to collect in one comprehensive volume a representative selection of ancient sources in translation, with commentary, on the history, institutions, society and economy of the Greek world from c. 750 to 338 BC - that is, the period best known and most important for the evolution of the polis, a form of political community which combined the aspects of city and state in a physical and psychological unity unparalleled either before or since. For us, the inheritors of much that the Greeks created, there is an inherent interest in the way in which they organised their society during these centuries. Although this book assumes no knowledge of Greek, the reader is introduced to a range of key Greek words and concepts which offer a direct insight into the mentality, both collective and individual, of the times. The sources themselves (all of which have been translated by the authors) are supported by introductory commentary, notes, bibliographies, chronological tables and maps. All students and teachers of the history of ancient Greece or of classical civilisation generally will find this book an invaluable tool.

The aim of this book is to collect in one comprehensive volume a representative selection of ancient sources in translation, with commentary, on the history, institutions, society and economy of the Greek world from c. 750 to 338 B.C. - that is, the period best known and most important for the evolution of the polis, a form of political community which combined the aspects of city and state in a physical and psychological unity unparalleled either before or since. For us, the inheritors of much that the Greeks created, there is an inherent interest in the way in which they organised their society during these centuries, in addition to what individual members of that society can still communicate to us, as individuals, through their writings. Although this book assumes no knowledge of Greek, the reader is introduced to a range of key Greek words and concepts which offer a direct insight into the mentality, both collective and individual, of the times. The sources themselves (all of which have been freshly translated by the authors) are supported by introductory commentary, notes, bibliographies, chronological tables and maps. All students and teachers of the history of ancient Greece or of classical civilisation generally will find this book an invaluable tool.
