| Term | Water potential |
|---|---|
| Definition | Water potential is the potential energy of water relative to pure free water (e.g. deionized water) in reference conditions. It quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects including surface tension. |
| Sampling medium | Surface water |
| Aggregation type | Average |
