Mechanical analyses of Buckner fine sandy loam. 



BUCKNER LOAM. 



The surface soil of the Buckner loam is a brown to dark-brown, 

 moderately friable loam, 14 inches deep, underlain by a brown to 

 dark-brown loam to fine sandy loam which in the lower part of the 

 3-foot section is slightly coarser textured and lighter colored. Ordi- 

 narily there is no sharp line of distinction between the surface soil 

 and subsoil, though in a few small spots the subsoil is a gray fine 

 sand or coarse sand, mottled with yellow. 



Tliis type occurs in numerous areas of varying size, scattered over 

 the terraces adjoining the Iowa River bottoms. The topography is 

 level to undulating, and the drainage good. 



This is the second most extensive of the Buckner soils, and is con- 

 sidered a good terrace soil. Corn, oats, hay, wheat, and rye are grown. 

 Under the prevailing farming methods corn yields 30 to 70 bushels 

 per acre, averaging 40 bushels; oats 30 to 70 bushels, averaging 45 

 bushels; hay three-fourths ton to If tons, averaging 1} tons; winter 

 wheat 10 to 38 bushels, averaging 23 bushels; and rye 8 to 23 bushels, 

 averaging 15 bushels. 



Land of this type sells for $135 to S210 an acre, averaging $150 

 an acre. 



BUCKNER SILT LOAM. 



The surface soil of the Buckner silt loam is a dark-brown friable 

 silt loam, in many places high in organic matter and occasionally 

 slightly gritty. At a depth of about 11 inches it is underlain by a 

 brown very fine sandy loam, which soon changes to grayish brown 

 mottled with yellow. Below 24 inches the color becomes light gray, 

 mottled with yellow to yellowish brown, and below 30 inches the 

 texture changes to a fine sandy loam. In some places the color and 

 texture of the subsoil vary from typical. 



Only a few small areas of this type are mapped. It occurs in asso- 

 ciation with the other Buckner soils. The topography is level, but 

 the drainage is good. The soil is farmed in the same w^ay as the 

 Buckner loam, and produces practically the same yields.
