Even within this rarefied atmosphere of intellectual achievements, his book \u003ci\u003eFactors of Soil Formation\u003c\/i\u003e stands out as a masterpiece. from the Foreword by Ronald Amundson, University of California at Berkeley\u003cbr\u003eHans Jenny (1899 1992), who taught at the University of California at Berkeley for 31 years, was a world authority on soils and soil formation. \u003ci\u003eFactors of Soil Formation\u003c\/i\u003e, his most influential work, is an advanced treatise on theoretical soil science. It has been said that this book, long considered a masterpiece of scientific methodology, had as great an impact on soil science as Charles Darwin's \u003ci\u003eThe Origin of Species\u003c\/i\u003e had on the study of evolution.\u003cbr\u003eThe book offers both a detailed discussion of the nature of the earth's terrestrial environment and a method of subdividing and studying it. The first two chapters are devoted to definitions and concepts, and methods of presentation of soil data. Chapters 3 through 7 explore the roles of time, parent material, topography, climate and organisms in the formation of soil. Chapter 8 presents conclusions.\u003cbr\u003eThough it was written more than 50 years ago, \u003ci\u003eFactors of Soil Formation\u003c\/i\u003e has not been superseded, nor has Jenny's theory of how soils and ecosystems form been replaced by new factorial theories. Students and professionals working in the fields of pedology, geology and ecology will find this clear, concise study, filled with many of Professor Jenny's own illustrations, stimulating reading.","brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":50205399941393,"sku":"CIN0486681289G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ LIKE_NEW \/ INTERNAL","offer_id":50906631733521,"sku":"GOR014117674","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":50929933320465,"sku":"GOR007902853","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":51975636910353,"sku":"GOR006107212","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ NEW \/ INGRAM","offer_id":53407847710993,"sku":"NIN9780486681283","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0486681289.jpg?v=1751293568"},{"product_id":"cymatics-book-hans-jenny-9781888138108","title":"Cymatics","description":"\u003cp\u003eCymatics is the study of sound-wave phenomena and this astonishing book vividly depicts the significance of audible sound throughout our world. It presents, primarily through beautiful photographs, the effects of sound vibrations to excite powders, pastes and liquids into life-like, flowing forms. The resultant patterns can be found throughout nature, art and architecture.\u003cbr\u003e \u003cbr\u003e This new expanded edition includes the two volumes originally published in 1967 and 1974, plus a new foreword by New York Times best-selling author, Ted Gioia, who has written extensively about the impact of music upon culture throughout history. An assortment of commentaries by leading researchers, artists, and scientists, reveal how Jenny's body of work has profoundly influenced a wide range of disciplines in the arts and sciences, particularly over the past twenty years.\u003cbr\u003e \u003cbr\u003e Dr Jenny's images are awe-inspiring because of their visual beauty and because they demonstrate a fundamental principle of creation; resonance: the inherent responsiveness of matter to vibration. Employing the phenomenological approach of Goethe and Rudolf Steiner, Jenny's keen observations and penetrating insights offer a uniquely comprehensive understanding of our world.\u003cbr\u003e \u003cbr\u003e The book is essential reading for students of sacred geometry, mandalas, metaphysics, sound healing and even crop circles.\u003c\/p\u003e","brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":50464781369617,"sku":"","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ GARDNERS","offer_id":50464782844177,"sku":"NGR9781888138108","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":51841327104273,"sku":"GOR014422662","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1888138106.jpg?v=1751412733"},{"product_id":"soil-scientist-teacher-and-scholar-book-hans-jenny-9781019230046","title":"Soil Scientist, Teacher, and Scholar","description":null,"brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":51015774404881,"sku":"","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":51015776469265,"sku":"NIN9781019230046","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1019230045.jpg?v=1750949657"},{"product_id":"soil-scientist-teacher-and-scholar-book-hans-jenny-9781019224755","title":"Soil Scientist, Teacher, and Scholar","description":null,"brand":"WoB","offers":[{"title":"US \/ NEW \/ INGRAM","offer_id":51015933985041,"sku":"NIN9781019224755","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1019224754.jpg?v=1750707794"},{"product_id":"soil-resource-book-hans-jenny-9781461261148","title":"The Soil Resource","description":"change is simply described by the rate of income and rate of loss. Our home's energy budget, our firm's inventory, our nation's debt, and humanity's numbers all have accounts that change at rates that are equal to the inputs minus the outputs. Jenny's system view of the soil was carried into the fertile fields of Midwestern American prairies from the laboratories of Switzerland in the late 1920s. Jenny's rate equations provided the other paradigm or world view that, I recall, brought us to the threshold of systems ecology as it later evolved in the second half of the twentieth century. As if world renown in the specialties of pedology and soil chemistry were not enough for one lifetime, excerpts below remind us that Hans Jenny has also been a perceptive outdoor field ecologist since his early Alpine expeditions with Braun- Blanquet in the mid 1920s. Jenny's ecosystem studies in the pygmy forest, a further classic example of a soil-plant system run down over hundreds of thousands of years since its origin, continue to occupy some of the vigorous retirement time near his farm in Mendocino County. But each specific, quantitative case study, and each research area conserved (with additional hard work) for further study by future generations, fits into Jenny's coherent world view. It is that view, and its legacies of discovery and of tangible landscape preserves, which we are privileged to share with their originator in this volume.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52144477962513,"sku":"NLS9781461261148","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781461261148.jpg?v=1757589121"},{"product_id":"south-west-africa-book-hans-jenny-9780949995117","title":"South West Africa","description":null,"brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":52153450365201,"sku":"GOR005625414","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780949995117.jpg?v=1757620231"}],"url":"https:\/\/www.worldofbooks.com\/en-gb\/collections\/author-books-by-hans-jenny.oembed","provider":"World of Books ","version":"1.0","type":"link"}
