SOILS AND FERTILIZERS 



32. Mechanical analysis of some typical soils. — When 

 soils are analyzed according to the mechanical separation 

 just described, there are shown to be great differences 

 between some of them, and soils that are adapted to certain 

 crops are found to have a somewhat characteristic composi- 

 tion. It must be remembered, however, that such dis- 

 tinctions are always limited by climate. The following 

 table, based on the work of the Bureau of Soils and the 

 Minnesota Experiment Station, contains a statement of the 

 mechanical analyses of a number of typical soils :
