.+w—JG G�ycvu�C 1,INI.ft. IIJ a 1Gvcl, vety IJUUI Iy drained soil. It occurs in bogs on plane or slightly con- cave side slopes on outwash plains and moraines. Indi- vidual areas range from 3 to 300 acres. This soil is subject to flooding from runoff from adjacent steeper • mineral soils. Typically, the surface layer is black muck about 7 inches thick. The middle layer is stratified dark brown to black mucky peat and muck about 36 inches thick. The bottom layer is very dark brown muck. In some places the entire profile is mucky peat. In a few places calcare- ous coprogenous earth occurs within a depth of 16 to 51 inches. Included in mapping are a few small areas of Cathro and Markey soils. Cathro soils are loamy within 51 inches of the surface, and Markey soils are sandy within 51 inches. Small islands of mineral soils are also includ- ed in mapping. This Seelyeville soil has moderately rapid permeability. Available water capacity is very high. Runoff is very slow. The organic matter content is very high. Natural fertility is low. A water table is commonly at a depth of less-than 2 feet. - - Most areas of this soil are left idle. Unless drained, it has poor potential for crops,hay, or pasture. It has poor potential as building sites and for sanitary facilities. It has good potential for wetland wildlife habitat. The high water table is the main limitation. If drained, this soil is suitable for hay, truck crops, and sod. Before bogs are drained they should be thoroughly investigated to determine the thickness of the muck deposits. The soil surface usually starts to settle after drainage is in- stalled. Frost often occurs early because of the low posi- tion on the landscape. Soil blowing can be a problem if row crops are grown. Undrained areas are suitable for pasture and hay if well managed. This soil is well suited to reed canarygrass because it forms a tough, dense sod that can support grazing animals and haying equipment even though the soils are partly wet. This soil is well suited to wetland wildlife habitat. Suit- able water habitat is easy to develop. Wetland food and cover crops can be expected to grow well. This soil is poorly suited to building site development and sanitary facilities. If this soil is to be used for build- ing, the organic material should be completely removed before fill is added. In some areas, foundations may need to be built on piling or slabs to overcome the soil limitations. This soil is subject to settling. It has very low strength for supporting foundations, is highly compress- ible, and has low bulk density. Some areas are suitable for parks and recreational areas, such as playgrounds and skating rinks. This soil is in capability subclass IVw. It is not placed • in a woodland suitability group.
