Soil is a complex, heterogeneous material composed of mineral particles, organic matter, water, and air. The mineral particles, which make up the bulk of the soil, are derived from the weathering of rocks and can range in size from clay minerals ( < 0.002 mm) to sand particles (0.05-2 mm) and gravel (2-64 mm). The arrangement of these particles and the pore spaces between them determine the soil's structure, which affects its physical properties and behavior.

Soil physics is a vital branch of soil science that deals with the physical properties and processes that occur in soils. It is an interdisciplinary field that combines concepts from physics, geology, biology, and engineering to understand the complex interactions between soil, water, air, and living organisms. In this piece, we will explore the fundamental principles of soil physics, drawing from the work of renowned soil physicist Daniel Hillel. Soil is a complex, heterogeneous material composed of
The fundamentals of soil physics, as explored in this piece, provide a critical foundation for understanding the complex interactions within the soil environment. By grasping these principles, we can better manage soils to ensure sustainable use, mitigate environmental problems, and promote ecosystem services. Daniel Hillel's work has significantly contributed to our understanding of soil physics, and his research continues to inspire new generations of soil scientists and environmental researchers.
