Integrating Soil Moisture Characteristics With Classification Units of Some Illinois Soils1
- L. J. Bartelli and
- D. B. Peters2
Soil moisture characteristics (15 atm., 1/3 atm., etc.) were determined for 31 soil types representing the major great soil groups recognized in Illinois. In addition such physical properties as bulk density and mechanical analysis were also determined for the principal soil horizons. Available soil moisture and field capacity was shown to vary by textural classes for each soil group studied. For example it was found that silt loam soils of the Gray-Brown Podzolic averaged more available moisture in the A horizon than the Brunizems and Planosols. It was found that the available soil mositure was highly correlated with the 1/3-atm. percentage but not correlated with the 15-atm. percentage. The available moisture was controlled principally by the silt fraction.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
