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.
