Since 1980, our understanding of the factors and processes governing the distribution of soils on the Earth’s surface has increased dramatically, as have the techniques for studying soil patterns. The approach used in this book relies on the National Resources Conservation Service databases to delineate the distribution of each of the eight diagnostic epipedons and 19 subsurface horizons, to identify the taxonomic level at which each of these horizons is used, to develop an understanding of the role of the factors and processes in their formation and to summarize our latest understanding of their genesis. A chapter is devoted to each diagnostic horizon (or combined horizons). This book is intended to serve as a textbook in soil geography, a reference book for geographers, ecologists and geologists and a tool for soil instructors, landlookers, mappers, classifiers and information technologists.

This book provides an overview of the distribution, properties, and function of soils in the U.S., including Alaska, Hawaii, and its Caribbean territories. It discusses the history of soil surveys and pedological research in the U.S., and offers general descriptions of the country’s climate, geology and geomorphology. For each Land Resource Region (LRR) – a geographic/ecological region of the country characterized by its own climate, geology, landscapes, soils, and agricultural practices – there is a chapter with details of the climate, geology, geomorphology, pre-settlement and current vegetation, and land use, as well as the distribution and properties of major soils including their genesis, classification, and management challenges. The final chapters address topics such as soils and humans, and the future challenges for soil science and soil surveys in the U.S. Maps of soil distribution, pedon descriptions, profile images, and tables of properties are included throughout the text.

Excerpt from Important Soils of the United States: Issued to Accompany a Collection of Soils and Subsoils (in 13 Boxes) For Use of Schools and Colleges Teaching Agriculture and Physical Geography The soils of the United States for purposes of classification grouped into seven soil provinces, covering the eastern half of United States, and six soil regions, covering the western half. 7 soil provinces differ in the petrographic and physical character the rock from which the soil material was derived, topography, vation, and in processes by which the soil material was accumulai The soil regions do not conform to differences in the mode of ori or method of transportation of soil material, but to great phys graphic regions, and the soils within each region differ in orig these differences being substantially the same as the differences t distinguish the different soil provinces.

This book introduces the reader to the Great Lakes and considers their soil-forming factors and processes, taxonomic structure of the soils, soil geography and pedodiversity, while also addressing the importance and protection of soils in the Great Lakes Coastal Zone. The Great Lakes are an important part of the USA and Canada. Home to 33 million people, including 90% of all Canadians, the Great Lakes account for 20% of the world’s surface freshwater and 90% of the USA’s freshwater. Key industries include shipping, steel and automobile production, energy generation, fishing, pulp and papermaking, agriculture, and recreation. To date, there has been no comprehensive inventory of the region’s soils, which are now subject to dramatic climate change and environmental degradation. This book was prepared using the US Department of Agriculture, Natural Resources Conservation Service databases, including the Web Soil Survey, Soil Series Extent Explorer, soil classification and characterization databases, and county soil surveys, supplemented by shoreline viewer software, the author’s independent research, consultation with colleagues, and survey trips around the Great Lakes.

Chapter 29: Soils and Soil Classification of the eBook Understanding Physical Geography. This eBook was written for students taking introductory Physical Geography taught at a college or university. For the chapters currently available on Google Play presentation slides (Powerpoint and Keynote format) and multiple choice test banks are available for Professors using my eBook in the classroom. Please contact me via email at [email protected] if you would like to have access to these resources. The various chapters of the Google Play version of Understanding Physical Geography are FREE for individual use in a non-classroom environment. This has been done to support life long learning. However, the content of Understanding Physical Geography is NOT FREE for use in college and university courses in countries that have a per capita GDP over $25,000 (US dollars) per year where more than three chapters are being used in the teaching of a course. More specifically, for university and college instructors using this work in such wealthier countries, in a credit-based course where a tuition fee is accessed, students should be instructed to purchase the paid version of this content on Google Play which is organized as one of six Parts (organized chapters). One exception to this request is a situation where a student is experiencing financial hardship. In this case, the student should use the individual chapters which are available from Google Play for free. The cost of these Parts works out to only $0.99 per chapter in USA dollars, a very small fee for my work. When the entire textbook (30 chapters) is finished its cost will be only $29.70 in USA dollars. This is far less expensive than similar textbooks from major academic publishing companies whose eBook are around $50.00 to $90.00. Further, revenue generated from the sale of this academic textbook will provide “the carrot” to entice me to continue working hard creating new and updated content. Thanks in advance to instructors and students who abide by these conditions. IMPORTANT - This Google Play version is best viewed with a computer using Google Chrome, Firefox or Apple Safari browsers.
