SUMMARY. 



The Norfolk sandy loam is an extensive soil type developed within 

 the lower lying portions of the Atlantic and eastern Gulf Coastal 

 Plains. 



It lies at varying altitudes from sea level up to 150 or 200 feet 

 above tide, but the greater part of the type is probably found between 

 altitudes of 50 and 150 feet. 



The surface of the Norfolk sandy loam is nearly level, undulating 

 or gently rolling, and there are no steep slopes or marked differences 

 of elevation within the different areas of the type. 



The surface soil of the Norfolk sandy loam is a gray or a pale- 

 yellow medium sand, having a depth of about 12 inches. This is 

 underlain to a depth of nearly 2 feet by a loamy sand or sandy loam 

 of a yellow color which grades downward into a friable yellow sandy 

 clay. 



The surface and subsoil drainage of the Norfolk sandy loam is 

 usually complete and adequate. 



The Norfolk sandy loam may be characterized as a fair general 

 farming soil in all of the areas where it occurs, and is particularly 

 well suited to the production of medium upland cotton in the more 

 southern States. It is also a type which may be utilized for the pro- 

 duction of the main truck crops of mid-season maturity. 



For the improvement of crop yields upon the Norfolk sandy loam 

 greater attention should be paid to the growing of the legumes, to be 

 used as green manures. For this purpose crimson clover is available 

 in the more northern States, and cowpeas, winter vetch, and the 

 velvet bean in the more southern States. Rye or winter oats may be 

 used for the same purpose. 



Among the truck crops, the Norfolk sandy loam is particularly 

 well adapted to the production of extra early Irish potatoes for the 

 northern market. It is also well suited to the production of sweet 

 potatoes, either as a general crop in the more southern States, or as a 

 special market-garden crop in the Northern States. Watermelons, 

 cantaloupes, cucumbers, tomatoes, and asparagus are well suited to 

 the type, while cabbage and squash are grown to a limited extent. 



Among the fruits, peaches and grapes are best suited to the Norfolk 

 sandy loam. 



In certain localities, peanuts, bright cigarette tobacco, and sugar 

 cane are grown upon the Norfolk sandy loam to good advantage. 



In the more northern trucking region, nearly all of the available 

 surface of the Norfolk sandy loam has been occupied for the produc-
