soils are found in all parts of the State, they are most common in the 

 southeastern quarter, and include Soil Management Groups 12 to 17. 



Area 5 ( purple ) . Scantic-Merrimac-Hollis. is a mixed area near the 

 coast. It contains patches of fine sandy loam and loam soils from glacial 

 till, from both schist and granite (mostly Groups 1 to 11) ; sandy soils 

 on bedded sand and gravel (mostly Groups 12 to 17) ; and silt loams 

 from materials laid down in ponds or in arms of the ocean (mostly Groups 

 23 to 28). 



Area 6 ( blue ) . Ondawa-Hadlev-Podunk. consists of soils formed on 

 river bottoms. These soils occur in narrow bands along streams in all parts 

 of the State. Because of the scale, onlv the larger areas are shown on the 

 map and are represented by Soil Management Groups 18 to 22. 



Soil Erosion 



Since the white man came into the State and started clearing the forest 

 from the land, some soil erosion has taken place. The removal of soil bv 

 water or wind is not extensive over the State as a whole. Where it does 

 occur, it is a serious problem. The soils of New Hampshire are not as 

 erodible as those in some other parts of the country. Most of the land in 

 the State has a protective cover of trees or grass which reduces the hazard. 

 Also, for four or five months during the winter, the ground is protected by 

 either being frozen or by a snow cover. 



Most sloping areas that have been used for crop production have 

 suffered some loss of soil. On these farms where the soil has been intensively 

 used, erosion is a serious problem. In general, however, erosion has not yet 

 caused severe damage to most fields, but if sloping fields remain in culti- 

 vation they should be protected by sound conservation measures to prevent
