vesipotentiaalia
Vesipotentiaalia, often translated as water potential, is a fundamental concept in plant physiology and soil science that describes the relative tendency of water to move from one area to another. It is a measure of the free energy of water per unit volume. Water naturally moves from an area of higher water potential to an area of lower water potential. This movement is driven by differences in pressure, solute concentration, and matric forces.
In the context of plants, water potential is crucial for understanding water uptake by roots, transport through
In soils, water potential is affected by both matric forces (adhesion of water to soil particles) and
