Here, s = Specific gravity of soil,
d = Depth of root zone,
Fc = Field capacity,
PWP = Permanent wilting point.
d = Depth of root zone,
Fc = Field capacity,
PWP = Permanent wilting point.

Root zone of crops grown in sandy loam soil is 100 cm. The volumetric soil moisture contents at field capacity and permanent wilting point are 30 % and 5 %, respectively. The critical value of available soil water is 50 %. Then What is available moisture?
Can anyone answer this with the explanation?

dw = sgd[Fc- PWP].
= 1.5x80x[0.25-0.15].
= 12.
= 1.5x80x[0.25-0.15].
= 12.
