ANALYSIS BY THE UNITED STATES BUREAU 143 



(520 Ib. P.) " Very poorly adapted to general farm crops, and little success 

 is attained with either corn or wheat, and none of the grasses do well. " (Report 

 for 1901, page 46.) 



Norfolk loam (Maryland) "is a mellow brown sandy loam to a depth of about 



9 inches. The subsoil to 36 inches is a medium to heavy loam, which is often 

 underlain by fine yellow sand. In the area from which the samples were 

 taken it has a slight elevation and is gently rolling. It is usually well drained. " 



(610 Ib. P.) "The principal crop grown is wheat, which yields 20 to 30 

 bushels per acre on the heaviest phase of the type in fair seasons and from 15 

 to 20 bushels on the lighter areas, these yields depending largely on the amount 

 of fertilizer used. ... It responds readily to applications of fertilizer and 

 lime." (Report for 1903, page 172.) 



Orangeburg sandy loam (Alabama), "locally called 'red lands,' is a brown 

 to a reddish brown light sandy loam, 4 to 15 inches deep, resting on a friable 

 brick -red sandy clay subsoil. The surface is rolling. It is generally well 

 drained, although there is a tendency to form a 'plow sole' or ' hardpan.'" 



(520 Ib. P.) "Practically all of this type is under cultivation, and is highly 

 prized for the production of cotton. The yields are not so high in some in- 

 stances as on the Houston clay and other prairie types, but it is considered a 

 safer soil from year to year than the prairie type. Cotton yields from one 

 half to i bale per acre. As much as ij bales per acre has been produced 

 where the land has been heavily fertilized. Very little corn is grown, as it is 

 claimed that the yields are generally light. The difficulty here, as with the 

 Orangeburg fine sandy loam, is that the soil proper is shallow." (Report for 

 1905, page 436.) 



In the same report (page 438) the Orangeburg fine sandy loam, 

 mentioned above, is described as follows: 



" Cotton is the principal crop grown on the Orangeburg fine sandy loam. 

 The yields range from one fourth to i bale per acre, depending upon the amount 

 of fertilizers used and the methods of cultivation. It is not considered a good 

 corn soil, and, as a result, not much corn is planted. Corn yields range from 



10 to 20 bushels per acre." 



Crowley silt loam (Louisiana) "usually has a surface of about 16 inches. It 

 is of a brown color when wet, but ash gray when dry. It is composed of fine 

 sand and silt, with sufficient clay to render it rather impervious. If stirred when 

 wet, it puddles somewhat. This soil is underlain by a clay of mottled brown 

 and yellow color, with brick -red streaks and blotches. The subsoil is highly 

 impervious and the surface level, so that the soil has very poor drainage. The 

 samples analyzed are from level prairies in southern Louisiana. " 



(1220 Ib. P.) "From the time that the Crowley silt loam was first cul- 

 tivated, rice has been the only crop to receive attention. Nothwithstanding 

 this continued annual cropping with the same crop, without attempting in any 

 way to maintain the productiveness of the soil, there has as yet been no de- 

 crease in yields." (Report for 1903, page 470.)
