The Soil Resource Origin and Behavior
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 "sy

This book is dedicated to my wife Jean Jenny in appreciation of her persistent, successful efforts-with important help from many supporters-to preserve for research and education the natural landscape areas: Apricum Hill laterite crust near lone, California Mt. Shasta mudflow research area Pygmy forest ecological staircase (Jug Handle Reserve) and others still in the slow process of acquisition.
Foreword: Hans Jenny and Fertile Soil Hans Jenny has an unusual capacity for originating ideas, applying them and communicating them to others. In any field of knowledge, truly original ideas are rare, and particularly those which are pursued to the point of stimulating an entire generation of scholars in the field. Hans Jenny has done precisely that for soil science. Those who are or have been privileged to be his colleagues, students and friends are deeply grateful. (I) PAUL

The soil resource is supporting a growing world. Hans Jenny's fertile imagination has supported the science of origin of soils. Now it supports a broadening and deepening of the foundations of ecology. Vignettes from Jenny's life story tell something of how these twin contributions came to pass. They illustrate how ideas and traditions can crossbreed with one another for hybrid vigor in the history of science. I hope they show a bit deeper insight into creativity than we can usually learn from leading architects of science. Historians of science can follow details in an Oral History of Jenny's life (7). The Editors of Ecological Studies and Springer-Verlag feel especially privileged to make available not only the present book as a major historic contribution to pedology and ecology, but also the following personal sidelights about how that contribution was created over a full lifetime
