Constantin Nikiforoff was educated by premier Russian soil scientists but fled after the 1917 revolution. A refugee with no formal credentials or documentation, he arrived in the USA in 1921. He was hired in 1927 and started surveying and studying soils across the country. He was erudite, critical, and wrote several influential papers. In some ways, he was ahead of his time; in others, his ideas were later proven incorrect. Yet, in all respects, he was a distinctive researcher whose work l...

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 la...

This book provides an up-to-date and comprehensive report on the soils of Wisconsin, a state that offers a rich tapestry of soils. It discusses the relevant soil forming factors and soil processes in detail and subsequently reviews the main soil regions and dominant soil orders, including paleosols and endemic and endangered soils. The last chapters address soils in a changing climate and provide an evaluation of their monetary value and crop yield potential. Richly illustrated, the book o...

Sandy soils cover approximately 900 million ha worldwide, and there are extensive areas of sandy soils under cultivation. Most sandy soils have high water permeability, low water-holding capacity, low ability to retain and exchange nutrients, weakly developed soil structure and they may be prone to erosion by wind. As irrigation is required for obtaining good crop yields, there is a risk of substantial leaching of nutrients and pesticides, and ground water depletion. Due to global pressure...

This book is about digital soil morphometrics which is defined as the application of tools and techniques for measuring, mapping and quantifying soil profile properties, and deriving depth functions of soil properties. The book is structured along four research topics: (i) Soil profile properties, (ii) Soil profile imaging, (iii) Soil depth functions, and (iv) Use and applications. The pedon is at the heart of digital soil morphometrics. The use of digital soil morphometrics exceeds the pe...

Few topics cut across the soil science discipline wider than research on soil carbon. This book contains 48 chapters that focus on novel and exciting aspects of soil carbon research from all over the world. It includes review papers by global leaders in soil carbon research, and the book ends with a list and discussion of global soil carbon research priorities.Chapters are loosely grouped in four sections:§ Soil carbon in space and time§ Soil carbon properties and pro...
