valleys through it and formed steep hanks on either side. More than one- 

 third of the acreage of these soils is on level or nearly level land, and an- 

 other third is only gently sloping. Nearly one third of the level land has 

 the water table close enough to the surface to classify the land as having 

 poor to very poor natural drainage. More than two fifths of the soils are 

 very sandy or gravelly, making them too droughty for use as ordinary 

 cropland or for pasture production, although they are better suited to the 

 growth of pine. Only one fourth of the land has no impeded natural drain- 

 age but still has a medium-textured soil which will hold sufficient moisture 

 for good plant growth. 



These Soil Management Groups comprise one half of the cropland 

 found on the outwash materials; yet this land is not free of limitations. 

 The presence of bedded sand and gravel within three or four feet of the 

 surface makes them more subject to drought than the neighboring upland 

 soils. Even with their gentle slope and their freedom from stone, they are 

 not used for cropland to the same extent as the stone-cleared soils on 

 glacial till. 



The soils developed on glacial outwash and river terraces are divided 

 into six management groups (12-17) as follows: 



12. Deep, very excessively drained loamv sands and sands. 



a. Fine sands 



b. Coarse sands and gravelly sands 



13. Deep, excessively drained sandy loams. 



a. Over beds of sand 



b. Over stratified gravel and sand 



14. Deep, well-drained fine sandv loams. 



a. Over beds of sand 



b. Over stratified gravel and sand 



15. Moderately well-drained sandy and fine sandy loams over sands 

 and gravel. 



16. Poorly drained sandy and fine sandy loams over sands and gravel. 



17. Very poorly drained sandy and fine sandv loams.
