Paperback. Condición: New. Print on Demand. This book by the author takes a fascinating look at the evolution of soil bacteriology and its impact on agricultural production. Throughout history, human civilization has relied on agriculture as its foundation, while at the same time, humanity's understanding of the natural world th…at sustains us has progressed at a glacial pace. This book explores the historical development of humanity's understanding of soil bacteriology in relation to crop production, beginning with the recent discovery that soil is alive with unseen microorganisms. The author explores the work of scientists who dedicated their lives to unraveling the mysteries of the microbial world, placing their work in the context of the broader development of scientific thought. Their discoveries and the knowledge gained have ultimately led to innovative agricultural techniques and methods that have allowed civilizations to flourish, particularly in locations where the challenges of food security are most prevalent. This book is a valuable resource for anyone interested in the history of science and agriculture, particularly the role of soil bacteriology in feeding the world's population.
