a Comparatively few farmers applied manure to the wheat land in McPherson County. When the 

 manure was prorated to all the farms in this group, the application amounted to one-half a ton per acre 

 and the charge made a total of $1 per acre. The cost of manure on this basis was approximately 5 per cent 

 of the operating expense.

VALUE OF PLOW LANDS. 



In view of the fact that it has been customary in some methods of 

 accounting to include interest on land as a cost, a table showing the 

 value of plow lands in the United States has been added for conven- 

 ience. To compute the approximate land charge for a particular 

 district, ascertain the usual interest rate for this region, then multiply 

 this rate by a valuation which appears to be fair for the land of land 

 devoted to the crop under consideration. It is assumed that Table 

 41 will afford some suggestions concerning the values for different 

 grades of land.
