ABSORPTION OF SALTS BY SOILS. 



131 



Amounts of potash absorbed by the same soil from different strengths 

 of different solutions of potash salts. 



From the results of this table it is seen that not only have 

 large amounts of potash been absorbed from all solutions but 

 much larger amounts from the phosphates than from any others. 

 Taking the mean amounts absorbed from the five solutions of 

 each kind .of salt, they stand as given in the next table. 



Mean amounts of potash absorbed by one soil from different salt 



solutions. 



In parts per million of soil.
