= Bound water
{wiki=Bound_water}
Bound water, also known as "bound moisture," refers to water that is tightly adhered to the surface of molecules or within the structure of materials, such as soil, food, and biological tissues. This water is not free to move or evaporate easily, in contrast to free water, which can be more freely available and mobile. In the context of soil, bound water exists in a thin layer around soil particles and is crucial for the hydration of plants and microorganisms.
