ABSORPTION OF SALTS BY SOILS. 



135 



Amounts of lime aid migneiia absorbed by the name soil from 

 different strength* of solution*. 



If there is brought into one table the mean values for the ab- 

 sorption of the several bases by one and the same soil, and from 

 the corresponding salts in solution, as found by Kullenberg, 

 the results will appear as below: 



Mean amounts of several bases absorbed by the same soil. 



It is here seen that potash has been held back in the soil in 

 much larger amounts than any other base, and lime to the 

 smallest extent. If a percentage comparison of positive radicles 

 is made, using the mean values of the three groups of deter- 

 minations comm'iOn to all bases, the values stand as here given
