Book Description
SIMPLE questions often help us to understand problems better; and I think it indispensable, at the beginning of this work, to ask a question which appears simple in the extreme: "What is grazing?" The answer is generally as follows: "Causing grass to be eaten by an animal." That is correct! But here is another answer which, to my mind, is more realistic: "Causing the grass and the animal to meet." Since this book is almost exclusively concerned with grazing by cattle, I propose the following definition to the reader, requesting him to allow it to become well impressed upon his mind: Grazing is the meeting of cow and grass. It is by satisfying as far as possible the demands of both parties that we will arrive at a rational grazing, which will provide us with maximum productivity on the part of the grass while at the same time allowing the cow to give optimum performance.

Book Description
This book by Messrs Voisin and Lecomte comes at the right moment. It is a synthesis of M. Voisin's important study, Grass Productivity. This manual presents the chief ideas of two specialists. Since they are also excellent practitioners, they have applied these ideas before recommending them. Their evocative picture of 'the meeting of cow and grass' poses the true problem of the management of grazed grass. For the farmer, the production of meat and milk is an act of industrial conversion. The 'machine' is the animal that converts raw vegetable matter into finished food products which are rich in calories and easy to assimilate. This 'machine' is complex because it is a living being; it can be improved--within limits. But its yield depends basically on the quality of the raw materials offered to it for conversion. I hope that their words will be heard and followed. [From the Introduction]

The Grass Crop

The Grass Crop PDF Author: M. Jones
Publisher: Springer Science & Business Media
ISBN: 9400911874
Category : Science
Languages : en
Pages : 377

Book Description
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 together some of this work in a review of what is primarily the ecophysiology of the temperate grass crop. Unlike other crops grown for their grain or vegatative parts, grass and grassland products are used almost entirely for the feeding of ruminant animals; the interaction of the sward and the animal thus adds an extra dimension to investigations of the productivity of grassland. No one author could adequately encompass the breadth of work covered in the book. Acknowledged experts have therefore been selected as contributors to provide an up-to-date review of their own specialized areas. Whilst multi author texts can cause problems of lack of uniformity of approach, each contributor has been made aware of the contents of the other chapters in an attempt both to provide continuity and to prevent glaring overlaps.

Perennial Grasses for Bioenergy and Bioproducts

Perennial Grasses for Bioenergy and Bioproducts PDF Author: Efthymia Alexopoulou
Publisher: Academic Press
ISBN: 0128129018
Category : Technology & Engineering
Languages : en
Pages : 308

Book Description
Perennial Grasses for Bioenergy and Bioproducts: Production, Uses, Sustainability and Markets for Giant Reed, Miscanthus, Switchgrass, Reed Canary Grass and Bamboo brings together a team of international authors to explore the current utilization, sustainability and future perspectives of perennial grasses in the bioeconomy. The book begins by examining the role of these crops as feedstock for bioenergy, in particular advanced biofuels and bioproducts. It then offers five chapters, each covering one perennial grass type, namely giant reed, miscanthus, switchgrass, reed canary grass and bamboo. The book covers their breeding, cultivation, harvesting, pre-treatment, economics and characterization. The book goes on to present the thermochemical conversion pathways for different types of feedstock. The last chapter explores issues concerning sustainability of perennial grasses, including their production in marginal lands. This thorough overview is a helpful reference for engineering researchers and professionals in the bioenergy sector, whose understanding of feedstock characterization, sustainability and production is critical in the development of conversion technologies. Those in the industrial crops sector will benefit from discussion of various issues surrounding crop production, which can guide their feedstock cultivation, harvesting and pre-treatment for specific conversion processes or end use. The book is also a useful resource for instructors and students in Masters and PhD programs in the area of biomass and energy crops. Policy makers and government agents involved in regulating the bioenergy and bioproducts sector will find comprehensive information to guide their decision making. - Explores the whole value chain of grassy feedstock for advanced biofuels and bioproducts, from cultivation to end use, including biomass characterization (physical properties, chemical composition, etc.) and conversion and sustainability - Examines the sustainability and economic factors related to perennial grasses and their conversion into biofuels and bioproducts - Includes a complete list of grasses relevant for energy uses, and tables with their current and expected future uses and markets

Soil, Grass, and Cancer

Book Description
Almost a half-century ago, André Voisin had already grasped the importance of elements of the soil and their effects on plants, and ultimately, animal and human life. He saw the hidden danger in the gross oversimplification of fertilization practices that use harsh chemicals and ignore the delicate balance of trace minerals and nutrients in the soil. In this volume Voisin issues a call to stand up and acknowledge our responsibilities for public health and protective medicine ¿ part of a concerted attempt to remove the causes of ill health, disease and, in particular, cancer.
