i) Ultimate wilting point
- at such a soil water content, the plant wilts and fails to regain life even
after addition of water to soil.
ii) Saturation capacity
Saturation Capacity (Maximum moisture holding capacity): It is defined as the
amount of water required to fill all the pore spaces between soil particles by
replacing all the air. It is inclusive of hygroscopic water, capillary water and
gravitational water. When the porosity of a soil sample is known the saturation
capacity can be expressed as equivalent depth of water in cm per meter of soil depth.
Example: If porosity of a soil sample is 50% by volume, the moisture in each meter
of a saturated soil is equivalent to 50 cm on the field surface.
