Download or read book Grass Productivity An Introduction to Rational Grazing written by Dr. Robert C. Worstell and published by Lulu.com. This book was released on 2015-01-13 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Cultural Landscapes of Universal Value written by Bernd von Droste and published by . This book was released on 1995 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cultural landscapes are at the interface between nature and culture. They represent the permanent interaction between humans and their environment, shaping the surface of the earth. With the rapid social and economic development cultural landscapes belong to the most fragile and threatened sites on earth. Adapted protection and proper management is urgently needed. Since 1992 outstanding cultural landscapes can be protected under the World Heritage Convention. Thus, the World Heritage Convention is the first international legal instrument recognizing and safeguarding this type of property for future generations. This important step has led to enhanced international and national recognition. The present volume aims to contribute to enhanced protection and management of cultural landscapes around the world. It furthermore highlights in a truly interdisciplinary approach some of the most outstanding cultural landscapes of universal value in their geocultural and environmental context.
