B) Determine the amount of plant available soil water in the top 2 ft of soil expressed as a depth of water in inches. C) Determine the drainable porosity in percent by weight and by volume. In the diagram below. water flows from a reservoir at the top of the column vertically down at steady state conditions. Measurements indicate that the volume of water flowing through the soil column in 1.5 hours is 9 cm'. The cross-sectional area is 8.8...

The flow of water through soil depends on the porosity of the
soli which is assumed to be normally distributed. To compare two
types of sandy soil n1=16 measurements are to be taken
on the porosity of soil A and n2=21 measurements are to
be taken on soil B Assume that the two sample variances
S12=
0.01, S22= 0.02.
(a) construct a 95% confidence interval for ratio of variances.
