water potential
1Water potential — is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects… …
2water potential — noun (botany) A measure of the free energy of water in a solution, eg in a cell or soil sample, and hence of its tendency to move by diffusion, osmosis or in vapour form • • • Main Entry: ↑water …
3water potential — The chemical potential (ie. free energy per mole) of water in plants. Water moves within plants from regions of high water potential to regions of lower water potential, ie. down gradient …
4water potential — The pressure gradient that induces the flow of water, particularly with reference to plant water uptake from the soil, comprising the net effects of suction, solutes and matric forces …
5Water retention curve — is the relationship between the water content, θ, and the soil water potential, ψ. This curve is characteristic for different types of soil, and is also called the soil moisture characteristic.It is used to predict the soil water storage, water… …

7Water retention — can refer to: *Edema or peripheral edema *Premenstrual water retention *A water retention curve for soil water potential …
8total soil-water potential — The sum of the energy related components of a soil water system; i.e., the sum of the gravitational, matric, and osmotic components [22] …
9Water content — Soil composition by phase: s soil (dry), v void (pores filled with water or air), w water, a air. V is volume, M is mass. Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture),… …
