,, ,, <br /> HOUGHTON SERIES <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 /> TAXONONIIC 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 staxed.) <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 KCI); 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 /> I muck(sapric material); about 5 percent fiber, a trace rubbed;weak medium granular <br /> structure;neutral (pH 7.0 in KCI);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 /> j 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 KCI). <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 /> , <br />
