From the preface Mechanical Technology in Agriculture places equal emphasis on the practical applications and theoretical understandings necessary for both occupational success and advanced education in the field of agricultural technology. A major goal of the book is to show the relationship between science mathematics and mechanical technology. A second major goal is to apply mathematics science and mechanical technology in the solution of agricultural problems. This book is intended for use by advanced secondary school agricultural education students community college students lower division university students and their teachers. In addition this book should be of benefit to farmers agribusiness persons and others interested in learning about mechanical technology in agriculture. 628 pp. …

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This is the first comprehensive study of an east African lake for thirty years. It represents the culmination of research expeditions which stretch back twenty years and is thus able to pick up long term changes which the individual research activities do not reveal. Lake Naivasha is a tropical lake whose natural fluctuations are now dwarfed by human impacts. Papers show how the irrigation for horticulture and power cooling has reduced the lake depth significantly; exotic arrivals have altered the plant community beyond recognition and its commercial value as a fishery and a tourist feature are reduced by over use. Despite this, the lake has considerable conservation value at present. It provides a different case study in the ever-growing library of the effects of human follies. Lake Naivasha has achieved global importance in the past ten years because its waters are used to sustain the largest horticultural industry in Africa. The book highlights its fragility under such pressure and points out the way towards sustainable use of the water and the ecosystem.…
