COMPOSITION AND SOLUBILITY OF SOIL CLASSES 85 



Table XIII 



This table illustrates, (1) The much greater solu- 

 bility of the fine particles in strong hydrochloric acid. 

 (2) That the absolute amount of food elements dis- 

 solved is greater in the fine-textured class than in the 

 coarse-textured class. (3) That the ratio of food ele- 

 ments dissolved to the aluminum and other refractory 

 constituents dissolved is narrower in the coarse than in 

 the fine-textured class. 



Failyer's results are summarized in the following 

 table.
