Plants growing on clay soils are better able to survive a drought, compared to sandy soils, for two reasons: (a) clay soils hold a larger amount of available water, and, (b) much of the available water is held at "higher" tension (that is, lower water potentials in the range of -7 to -15 bars, for example)

True/False

It is good to be able to interconvert units for soil water potential, because data sources use a variety of units. Soil water potentials can vary from zero at a free-water surface to 100,000 cm of water in a very dry soil. Please convert a soil water potential of 7,526 cm of water to its equivalent soil water potential in bars.

It is good to be able to interconvert units for soil water potential, because data sources use a variety of units. Soil water potentials can vary from zero at a free-water surface to -10,000 kPa in a very dry soil. Please convert a soil water potential of -4,708 kPa to its equivalent soil water potential in cm of water.
