The water in the soil which is in excess of the hygroscopic and capillary water and which can move freely
downwards when the soil is porous and drainage available is called-
-
A.
Hygrosopic water
-
B.
Free water
-
C.
Firing water
-
D.
Capillary water
Correct Answer:
B. Free water
Explanation:
Free water, also known as gravitational water, refers to the moisture that exceeds the soil's capacity to hold it through hygroscopic or capillary forces. This water occupies the larger macropores and moves downward through the soil profile due to gravity when the soil is porous and drainage is available. Unlike hygroscopic water, which is tightly bound to soil particles, or capillary water, which is held in smaller pores by surface tension, free water drains away until the soil reaches field capacity. While it can contribute to groundwater recharge, it is typically only available to plants for a short duration as it passes through the root zone.
