of truck crops. Strawberries lead in acreage within the area mapped. 

 Potatoes and cabbage are the other important spring crops; spinach 

 leads among winter crops. Kale is grown to a small extent. 



The Norfolk fine sandy loam is the most important trucking soil 

 encountered in the surveys or in the district. It occurs chiefly upon 

 level, well-drained uplands, contiguous to tidewater. Within the 

 limits of the detailed surveys, over 90 per cent of its area is under 

 cultivation. In the spring practically all of this area is used for 

 truck crop production. In the late summer and early fall, forage 

 crops occupy rather more than one-half its extent. Potatoes are the 

 most important spring truck crop on the Norfolk fine sandy loam, 

 occupying 58.6 per cent of the part of the type included in the de- 

 tailed survey. It is safe to say that they constitute at least one-half 

 of the spring truck crop acreage on the type throughout the Norfolk 

 district. Cabbage is second in importance, covering 10 per cent of 

 the area surveyed. Snap beans and strawberries cover the other 

 important areas. Among fall and winter truck crops, kale is by far 

 the most important on the Norfolk fine sandy loam in the Church- 

 land area and it is extensively grown on the type in the district. 

 Fall crops of potatoes and spinach are next in importance. 



Norfolk loam, extensively developed within the limits of the Dia- 

 mond Springs area and in the general district, is usually found upon 

 level uplands or slight ridges and is moderately well drained in its 

 natural condition. Within the limits of the detailed survey less than 

 one-third of its area is cleared and commonly used for crop produc- 

 tion. Over 40 per cent is in forest or cut-over land, and a consider- 

 able part of the land once cleared is not regularly used for cropping. 

 In the general district it is probable that a somewhat larger propor- 

 tion of the type is regularly tilled, chiefly to general farm crops. 

 Within the area surveyed about one-half of the cropped area is occu- 

 pied by forage crops and one-half by truck crops. Among these, 

 strawberries are of greatest extent, and small areas of cabbage, pota- 

 toes, and spinach are also grown. Corn, either grown alone or with 

 cowpeas interplanted, is the most important forage crop. Corn, 

 cowpeas, winter oats, sorghum, and even cotton are produced on this 

 type within the district 



The Norfolk gravelly loam is of small extent, either in the areas 

 surveyed or in the district as a whole. It occurs as small areas 

 chiefly associated with the Norfolk loam. About one-half of its area 

 in the Diamond Springs area is cleared and cropped. This is greater 

 than the normal proportion. The type is not desired as truck soil 

 and its chief use for such purposes is made by colored farmers. Lima 

 beans, strawberries, early potatoes, and some spinach are grown. 

 Corn is the most important forage crop, occupying the largest area 

 of any of the crops grown.
