' <br /> ' <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 /> ' TAXONOMIC CLASS: Euic, mesic Typic Haplosaprists <br /> TYPICAL PEDON: Houghton muck - on a level area in a cultivated field.
