BULLETIN 1005, XJ. S. DEPARTMENT OF AGRICULTURE. 



In the Churchland area the fall crops are somewhat concentrated 

 on the Sassafras and Norfolk fine sandy loams. Kale and spinach 

 are especially segregated on these types, while the fall potato crop 

 occurs on the Norfolk and Keyport fine sandy loams. 



In the Diamond Springs area nearly 70 per cent of the total acreage 

 of fall and winter truck crops is found on the four best-drained 

 soils, 51 per cent occurring on the two coarse sandy loams. 



It thus appears that the growing of truck crops upon the different 

 soils of the Norfolk trucking district is most strongly affected by 

 drainage conditions resulting (1) from the texture of the soil types 

 and (2) from the physical position of the soils with regard to natural 

 or artificial outlets for drainage waters. 



This results in the utilization of the coarser-grained and better 

 drained types for the growing of winter crops or those which occupy 

 the ground throughout the year; in the use of soils of intermediate 

 texture, like the fine sandy loams for the growing of large areas of 

 spring truck crops; and in the use of the loam soils and others of less 

 perfect drainage for the growing oi forage crops or in their remaining 

 out of cultivation. The notable exception to this general condition 

 is found in the case of the Sassafras loam. This type is naturally 

 well drained and has been utilized extensively for truck crop pro- 

 duction, although its texture is somewhat fine grained for such 

 use. 



Tables VI and VII show in detail the more important uses of each 

 extensive soil type for the production of each important truck crop 

 in spring and fall, respectively.
