The bulk density of the fully saturated soil is 1.75 g/cm 3 , and the density of water is 1 g/cm 3 . After a soil sample is drained by gravity, the weight of the soil sample is 800 g. After the sample is oven-dried, the sample weighs 700 g. Assuming water that was drained by gravity is 250 g, Calculate the porosity, specific yield and specific retention of the sample.
