How soil particles hold onto water against the force of gravity.
Daniel Hillel was a World Food Prize laureate and a pioneer in the field of soil physics. His approach shifted the focus from purely mechanical views of soil to a more holistic, "systems-based" perspective. He emphasized that soil is not just "dirt," but a dynamic interface between the atmosphere, the hydrosphere, and the biosphere.

You might ask: Is a soil physics book from the 1980s still relevant? Absolutely. Climate change is amplifying droughts and floods. Understanding infiltration (how fast water enters soil) and available water capacity (how much water soil stores for plants) is vital for climate-resilient agriculture.
