The primary audience for this book are students of borderline sciences, for whom a solid understanding of soil science is crucial. These individuals often find themselves overwhelmed by texts that are too complex and unable to provide a clear picture of soil. This book is written in a way that is accessible to the intelligent layman who has an interest or stake in the soil, and does not assume prior knowledge of chemistry. The aim of this book is not only to serve as a textbook, but also to foster a broader interest in soil improvement and its role in agriculture. Ultimately, it is hoped that this book will contribute to a more intelligent and responsible use of this valuable natural resource.
