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.
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.
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...
