\<@27\>Geographically Associated Soils

-   \<@29\>Cowarts soils, which have a fine-loamy particle-size control
    section, are well drained, and have a thinner solum than that of the
    Susquehanna soils

    than that of the Susquehanna soils

-   \<@29\>Telfair soils, which are moderately well drained and have a
    solum that ranges from 20 to 40 inches in thickness

-   \<@29\>Wicksburg soils, which are well drained and have an argillic
    horizon within a depth of 20 to 40 inches

\<@27\>Typical Pedon
