Capillary Potential –
the tendency which the soil hold the capillary water is measured in term of the capillary potential.
it defined as work done to take water from the mass of soil.
dear friends, we know the Capillary force is negative so we can relate it with capillary potential and say its always negative and max value is zero.
From the Capillary water tension we now when water content decreases the tension increase. from these we say
when water content minimum the capillary potential is minimum.
Capillary Siphoning Definition
capillary siphoning is prevented by increasing the height of the impervious core above the capillary range.
