HOUGHTON SERIE S <br /> The Houghton series consists of very deep, very poorly drained soils formed in <br /> herbaceous organic deposits more than 51 inches thick in depressions on lake plains, <br /> outwash plains, ground and end moraines and on floodplains. These soils have <br /> moderately slow to moderately rapid permeability. Slope ranges from 0 to 2 percent. <br /> Mean annual precipitation is about 35 inches, and mean annual temperature is about 50 <br /> degrees F. <br /> TAXONOMIC CLASS: Euic, mesic Typic Haplosaprists <br /> TYPICAL PEDON: Houghton muck-on a level area in a cultivated field. (Colors are <br /> for moist soils unless otherwise stated.) <br /> Oal--O to 9 inches; black(N 2.5/0)broken face and rubbed muck(sapric material); about <br /> 5 percent fiber, a trace rubbed; weak coarse subangular blocky structure; neutral (pH 7.0 <br /> in KCl); abrupt smooth boundary. <br /> Oa2--9 to 13 inches; black(N 2.5/0) broken face, very dark brown(7.SYR 2/2)rubbed <br /> muck(sapric material); about 5 percent fiber, a trace rubbed; weak medium granular <br /> structure; neutral (pH 7.0 in KCl); abrupt smooth boundary. <br /> Oa3--13 to 24 inches; dark reddish brown(SYR 3/2) broken face, dark reddish brown <br />(SYR 2/2)rubbed muck(sapric material); about 15 percent fiber, less than 5 percent <br /> rubbed; massive, breaking to thick platy fragments; neutral (pH 7.0 KCl); abrupt smooth <br /> boundary. <br /> Oa4--24 to 32 inches; black(SYR 2/1)broken face and rubbed muck(sapric material); <br /> about 10 percent fiber, a trace rubbed;massive; about 1 percent woody fragments; neutral <br />(pH 7.0 in KCl); clear wavy boundary. <br /> Oa5--32 to 48 inches; dark reddish brown(SYR 2/2)broken face,black(SYR 2/1) <br /> rubbed muck(Sapric material); about 20 percent fiber, less than 10 percent rubbed; <br /> massive, breaking to thick platy fragments; neutral (pH 7.0 in KCl); abrupt smooth <br /> boundary. <br /> Oa6--48 to 80 inches; dark reddish brown(SYR 2/2) broken face and rubbed muck <br />(sapric material); about 10 percent fiber, less than 10 percent rubbed; massive; slightly <br /> sticky; about 15 percent mineral soil; neutral (pH '7.0 in KCl). <br /> TYPE LOCATION: Clinton County, Michigan; about 3 miles northeast of the village of <br /> Bath; 200 feet north and 400 feet east of the southwest corner of sec. 12, T. 5 N., R. 1 W. <br /> USGS Bath topographic quadrangle, lat. 42 degrees 49 minutes 43.4 seconds N. and long. <br /> 84 degrees 52 minutes 56.9 seconds W.;NAD 27. <br /> RANGE IN CHARACTERISTICS: The organic layers are more than 51 inches thick. <br /> The organic fibers are derived primarily from herbaceous plants, but some pedons <br /> contain individual layers which contain as much as 30 percent woody material, however, <br />
