Water held by fine-grained soil particles due to electrochemical force of adhesion is known as:
Show Hint
For soil water classification: - Adsorbed water: Electrochemical adhesion. -Capillary water: Held in pores by surface tension. - Free water: Gravitational water.
Electrochemical forces tightly bind adsorbed water to soil particles, forming an immobile, thin layer around them. While this water does not flow through the soil, it is crucial for soil cohesion and structure.
