<br />annual nit temperature is -18° to 52° F., and the frost-
<br />free season is about 1.19 to 155 days.
<br />In a representatic-e profile the surface layer is dark

<br />about lI sashes thick, tLat is wottle4 in the loner part.
<br />The underlying material that estends to a depth of 60
<br />inches or more is pale-bronn grat•elly sand that contains
<br />tnanr• mottles. In the surface layer, soil reaction is mildly
<br />alkaline, and below this, it is neutral.
<br />Siwot soils bare modelste permeability. .available
<br />Hater capacity for the profile is lore to moderate. Roots
<br />can penetrate to a depth of BO inches or more, and the
<br />seasonal high Rater table is at a depth of between 6 and
<br />18 inches.
<br />Most of this acrea~m is used for pasture. Some small

<br />Tlie profile of these soils is much like the one described

<br />variable in testure. This ]ar-er ran_es front sandy clan

<br />Included with these soils in mappinm are small. almost

<br />included are tmn:uned soils that are sandy. These includ-
<br />ed soils an(l ~ ores buts ma1:e up 15 percent of each
<br />mapped area.
<br />Runoff is slog on these soils. The erosion hazard is
<br />sli_ht escept for back cuttin_ near channels. Because of
<br />their position in the landscape. these soils are frequently
<br />flooded. They bare a seasonal high water table.
<br />Because of the hi_h water table an(l the (lepth to sand
<br />or grouch these soils are best suited for use as pasture or
<br />meadow. These soils are also suitable as a site for gravel
<br />pits. In some places a fen small areas are used for irri-
<br />_>:tted crops. These are :wens that are more cout•enient to
<br />farm thmt to plant to grass. (Capabilit}- units I~"n--1,
