¹The whole-soil bulk density was not measured. It was calculated using 1.45 g/cc as the 1/3-bar bulk density of the less-than-2-mm fraction for mineral soils.
³The saturated whole-soil bulk density was not measured. It was calculated using 1.45 g/cc as the 1/3-bar bulk density of the less-than-2-mm fraction for mineral soils.
