| Abstract: | A profilometer was constructed to measure changes occurring in the potato soil bed profile during growth of a potato crop. Changes in bed cross sectional area were found to be closely related to changes in soil bulk density and air permeability. The instrument was helpful in rapid approximation of these parameters of the physical condition of a Hesperia sandy loam soil. |
