Soil is a finite resource, and its degradation is irreversible within a human lifetime. The degradation of soils has a significant impact on the food we eat, the water we drink, the air we breathe, and the health of all living organisms on the planet. Approximately 95% of our food is produced on soils, directly or indirectly. Without healthy soils, we would not be able to meet our food, fiber, and fodder requirements.

The book provides a comprehensive understanding of soil, covering its nature, properties, and functions. It presents all basic information about soils in a logical sequence, from the definition of soil to its formation, the factors and processes governing its formation, its intrinsic properties, classification, functions, and the role it plays in the global environment today and for a sustainable future. Emphasis has been placed on soil quality and soil health care, as it is a critical issue facing society.

The 32 chapters of the book offer a wealth of information for those who are new to the study of soils and wish to gain a deeper understanding of the subject.
