<br />Stoneham Series
<br />The Stoneham series consists of well-drained, Ileal•ly
<br />level to ntodcrntely sloping soils on uplands. These soils
<br />formed in loamy, old alhrvinl material.
<br />In a representative profile (fig. 11), tha surface layer
<br />is light grayish-brown loam about 5 inches thick. It is
<br />noncalcnreous. The subsoil is brown sandy clay loom
<br />about 8 inches thick. It is noncalcnreous. The underlying
<br />nlnterial is light-gray, sandy loom ntld gravelly loom
<br />that is hig}lly cnlcnreous. At a depth of 30 inches, it is
<br />pale-brown gravelly sandy loom tllnt is highly cal-
<br />careous. It extends to n depth of about GO iltclles.
<br />Stoneham soils absorb water at n moderate rata and
<br />the available water capacity is nlodernte. Perlncabilit.y
<br />is moderate, and the entire soil is suitable for roots.

<br />Stoneham loam, 0 to 3 percent slopes 15181.-This soil
<br />is in scattered areas along major stream channels in the
<br />count}'- It is a71 uplands back from the stream channels.
<br />The areas arc irregular in shape and range from 30 to 50
<br />acres ill size. Tltis soil has n profile similar to the one
<br />described as representative for the series, but it has a
<br />thicker surface layer and subsoil. Runoff is medium
<br />to slo+v. lVatcr erosion and soil blowing ere moderate
<br />hazards. Included in mapping ore a few small areas of
<br />Platncr loam that commonly are in small depressional
<br />wrens.
<br />llfost areas of this soil are cultivated, but n felt'
<br />Wrens remain in native grass. Capability unit IVe-3,
<br />nonirrignted; Loamy Plains range site, tree planting
<br />suitnbiLty group 1.
<br />Stopeham loam, 3 to 9 percent slopes (SrDI.-This soil
<br />has the profile described as representative for the series.
<br />It is on uplands near major stream channels in scattered
<br />areas throughout the county. The Wrens are uniform in
<br />shape and range from 50 to BO acres in size. Runoff is
<br />generally medium but is rapid if rile soil is unprotected.
<br />The hazards of water erosion and soil blowing me severe
<br />in cultivated wrens. Gullies form in drninnge~rnys in same
<br />places. Included in innllping arc small nrcas of send
<br />and grnvcl deposits and n few small nrcas of Ascalon
<br />SONS.
<br />illost areas of this sail ore cultivated, but. same wrens
<br />have a cover of native grass. Capability snit VIe-1, non-
<br />irri~nted; Loamy Plains range site; trce planting suit-
