For a soil sample with bulk density of 1.10 g/cm³, please calculate the maximum possible volumetric water content, in cm³ water/cm³ dry bulk soil. Please assume a particle density of 2.65 g/cm³.

 

For a soil sample with bulk density of 1.14 g/cm³, please calculate the maximum possible gravimatric water content, in g water/g dry soil. Please assume a particle density of 2.65 g/cm³. Hint: Calculate both g water at saturation and g dry soil for a 1 cm³ volume!

 

In two adjacent fields the texture of one soil is sand and the other is clay loam. A soaking rain occurs and after two days or so both soils are at field capacity. At this time soil water potential:

A.is most negative in the clay loam soil

B.is the same in both

C.is most negative in the sandy soil
