A Bennington Silt Loam Profile
Grey-Brown Podzolic characteristics are well expressed in the Bennington
soils. The surface soil is dark gray silt loam or fine sandy loam about four inches
thick in uncultivated areas. On cultivation a part of the subsurface is mixed with
the surface to form a thicker, slightly browner surface layer. The Ae horizons are
about 20 inches thick, their yellowish brown color becoming lighter in depth. A
horizon which has characteristics of both the A and B horizons underlies the Ae
horizons. This is about 10 inches thick, light brown in color and is called the A/B
horizon. The Bt horizon is dark brown, contains more clay than any other horizon
in the solum and is located immediately above the clay loam till. The till is calcareous
and occurs at a depth of about 32 inches.
The Bennington soils are used chiefly for livestock raising and dairying.
Cereal grains, hay and pasture are the main crops grown and yields are high
where soil fertility is maintained.
TAVISTOCK SERIES
The Tavistock soils, imperfectly drained associates of the Bennington soils,
occur on gently undulating areas where surface runoff is low and permeability
is slow. The material from which these soils have been derived is the same as that
of the Bennington series.
