Proceedings Of The Xiv International Grassland Congress
Approximately 1500 scientists from around the globe participated in the InternationalGrassland Congress at the University of Kentucky in 1981, sharing existingknowledge of grasslands and exploring methods for increasing the productivity oflivestock/forage systems so as to better feed mankind while maintaining or improvingenvironmental quality. Of the nearly 500 papers presented on previously unpublishedoriginal research or experimental research and development projects, 273 were selectedfor inclusion in this book. They cover the current basic and applied research on productionand utilization of forages from grasslands the world over.
The Grass Crop
Grass is a very important world crop. In some countries, for example the UK, Australia and New Zealand, animal products from grassland make a greater contribution to the value of agricultural production than does any other crop. Yet research being undertaken to further· our understanding of the factors affecting the growth and productivity of grasslands has trailed in the shadow of the determined efforts made to improve our knowledge of cereals and, to a somewhat lesser extent, legumes. However, in spite of its low profile, grassland research has resulted in considerable advances in our knowledge in the last 20 years, and we feel that this book provides a timely opportunity to bring togethe...
Nutrient Elements in Grassland
This book is an essential reference source covering the chemical elements that are nutrients for plants or grazing animals. It deals with the concentrations and transformations of these elements in soils, grassland plants, and ruminant animals, particularly cattle and sheep. For each element, the following data are given: forms occurring in soil, factors that affect availability and concentration, uptake and distribution in grassland plants, role in animal nutrition, amounts and forms excreted by grazing animals, and concentrations needed by ruminant animals.

Recent Developments in Ruminant Nutrition – 2
Recent Developments in Ruminant Nutrition – 2 presents papers that discuss the advances in the different areas of ruminant nutrition. The book is comprised of 22 chapters that discuss topics such as milk production, health, and nutrition. The coverage of the text includes meeting the nutrient requirements of beef cattle in forage-based systems of production; nutrient requirements of intensively reared beef cattle; and feeding for high margins in dairy cows. The book also tackles issues concerning milk production such as photoperiodic influences on milk production in dairy cows; manipulation of milk yield with growth hormone; and the influence of level and pattern of concentrate input on milk output. The text will be of great use to researchers and professionals in the animal husbandry industry.
Principles and Measurements in Environmental Biology
Principles and Measurements in Environmental Biology aims to provide an understanding of some important physical principles and their application in biology. The book also aims to describe how instruments utilizing these principles can be used to measure biological and environmental processes and their interactions. This book covers the effects of the environment on biological organisms; the application of theories of radiation, kinetic theory, gas laws, and diffusion in biology; and water and its properties. The relation of plants with atmosphere near the ground is also discussed. This book also presents sampling techniques; the computation of errors used in the interpretation of data; the use of different devices; and data gathering and its practical applications. This text is for students, researchers, and professionals and experts in biology who wish to understand the mentioned principles in physics, its mathematical aspects, and their applications in the field.
Physiological Processes Limiting Plant Productivity
Physiological Processes Limiting Plant Productivity presents the proceedings of the Thirtieth University of Nottingham Easter School in Agricultural Science held at Sutton Bonington in England on April 2-5, 1979. Contributors focus on physiological processes limiting plant growth and development in the context of agricultural productivity. Emphasis is placed on the fundamental mechanisms that underlie crop production and their control. This text is comprised of 20 chapters; the first of which discusses the genetics of crop physiology in relation to agricultural production. The range of problems that plant physiologists must address is considered, followed by an assessment of what is happenin...
