<br />Truckton Series
<br />'1'hr. '1'ruclaon series consists of well-drained to some-
<br />tchat'~rz~:essivcly drained, nearly level to moderately
<br />slol~in~ ,oils on uplands. These soils formed in ~wind-
<br />wnrl;crl snarly material. ~
<br />In a rvpresrntntivo profile, the sm•fnce layer is grnyish-
<br />brmvn :uul dark grayish-brown loamy sand about 0
<br />inches thick. It is noncnlcareous. The upper pert of the
<br />snlisnil is d;ul:-brown and brown snntly loam about 12
<br />inches thii•h.- Tt, is nmlcalcnreous. The lower part of
<br />the subsoil is yellowish-brown ]onmy sand about 11
<br />int•Ites title]:. It is noncnlcnreous. The underlying ma•
<br />terin] is ycllnwish-brown coarse sand that extends to a
<br />ilcpth uC Gtr in;:hes or more.
<br />'1'rwJ;ton soils absorb [eater rapidly, and the nvai]-
<br />aLlc venter capacity is low. Pcrmenbility is rapid, and
<br />tho entire soil is suitable for roots.

<br />Truckton loamy sand, 0 to 3 percent slopes ITIBI.-
<br />This soil is mainly along major stream channels. It Las

<br />Included in mapping are small Wrens of I3lnkcltind

<br />top of slopes, and this Truckton soil is on the gentle
<br />side slopes.

<br />strongly sloping areas have a cover of native grass. The
<br />soil is generally unsuitable for cult.ivntimt and is better
