Book Description
This book narrates how the study of the soil became a science and institutionalized in the USA between 1860 and 1960. The story meanders through the activities, ideas, publications, and correspondence of people who influenced the progressions, that led to the budding and early blossoming of American and international soil science. Interwoven is a tale of two farm boys who grew up 900 km apart in the Midwest USA in the late 1800s and early 1900s. Emil Truog and Charles Kellogg met in the late 1920s and shared a natural connection to the soil. Both were practical pioneers and believed that understanding soils was crucial to helping people on the land make a better living. The USA is a big country, its soil science is geographically intertwined, and the cradle of its history primes back to a few people. “Soil Science Americana is an intellectual biography, not of one individual but of a new scientific field from its emergence to its complete coming of age.” — Louise O. Fresco, President, Wageningen University and Research “In a lively, personal voice, Hartemink traces the roots of modern soil science in the United States...creating a book that will engage both the expert and non-expert in the underappreciated field of soil science.” — Jo Handelsman, Director, Wisconsin Institute for Discovery “The intellectual master piece is of interest to soil scientists, general public and the policy makers, and will remain pertinent for generations to come.” — Rattan Lal, World Food Prize Laureate 2020, The Ohio State University

Book Description
It has long been recognized that soil organic matter is the key to soil fertility. As a nutrient store it gradually provides essential elements which the soil cannot retain for long in inorganic form. It buffers growing plants against sudden changes in their chemical environment and preserves moisture in times of drought. It keeps the soil in a friable, easily penetrated physical condition, well-aerated and free draining, providing young seedlings with an excellent medium for growth. But it has another property, the nature and extent of which have been the subject of argu ment and controversy ever since scientists began to study the soil, and that is its ability to affect growth directly, other than by providing nutrient elements. Any one wishing to learn about these effects has been faced with a daunting mass of literature, some confusing, often contradictory, and spread through a multitude of journals. Individual aspects have been covered from time to time in reviews but there has obviously been a need for a modern authoritative text book dealing with the many facets of this subject, so the publication of this volume is timely. The editors and authors are all specialists in their fields, fully familiar with the com plex nature of soil organic matter and with the particular difficulties arising in any study of its properties. Where controversies exist they have presented all sides of the argument and have highlighted areas where further work is badly needed.
