The eighth edition is a major revision in which there has been
careful revision of the topics covered as well as changes in the
depth of coverage. Many new figures and tables are included.
Summary statements are given at the ends of the more difficult
sections within chapters, and a summary appears at the end of each
chapter. Many nonagricultural examples are included to emphasize
the importance of soil properties when soils are used in
engineering and urban settings. The topics relating to
environmental quality are found throughout the book to add interest
to many chapters. Several examples of computer application are
included.
