sy+sr = n
sy = 0.30 - 0.10 = 0.20.
sy = volume of water/volume of soil.
Volume of soil = volume of water * volume of soil.
Volume of soil = 50*3*0.2 = 30.
sy = 0.30 - 0.10 = 0.20.
sy = volume of water/volume of soil.
Volume of soil = volume of water * volume of soil.
Volume of soil = 50*3*0.2 = 30.

Porosity = Specific yeild + Specific Retention
.30= specific yeild + .10.
Spy = .20.
Then .20*50" * 3.
= 30.
.30= specific yeild + .10.
Spy = .20.
Then .20*50" * 3.
= 30.
