Taft Silt Loam
Taft Silt Loam is a somewhat poorly drained soil on low lying terraces along
creeks. Normally the plow layer is dark grayish-brown, friable slit loam. The
upper part of the subsoil is mottled brownish-gray and yellowish-brown, friable silty clay
loam. The lower part is mottled gray, brown, and olive silty clay loam that is
compact and brittle. This lower part, which begins at a depth of 14 to 21 inches, is
a fragipan. It limits the depth of the root zone and restricts the movement of
water.
The plow layer is low in organic matter content but nevertheless is easy to
till. It can be plowed and cultivated under ideal moisture conditions during a short
time only. Most of the time it is too wet. The natural fertility is moderately
low, but the wetness is a more limiting factor. The reaction is strongly acid.
The moisture-supplying capacity is moderately low, and crop yields generally are reduced
because of insufficient moisture.
This soil is not subject to erosion, so under good management it can be cultivated
continuously. The choice of crops, however, are limited. The most suitable are
those that tolerate some wetness. Surface drainage helps to remove excess water.
