T. Lyttleton Lyon and James A. Bizzell 



bring about an acid condition of the soil. The amounts removed from 

 planted and from unplanted soil are given in table 50: 



TABLE 50. Average Annual Removal of Sodium from Planted and from 



Unplanted Tanks 



(In pounds per acre) 



Effect of lime on removal of sodium 



The application of lime to this soil depressed the loss of sodium, as 

 is seen in table 51: 



TABLE 51. Average Annual Removal of Sodium from Limed and from 



Unlimed Tanks 



(In pounds per acre) 



Not only in the drainage water was there a smaller removal of sodium 

 from the limed soil than from the unlimed, but also in the crops. Sodium 

 resembles potassium in this respect, but its conservation was even more 

 marked in spite of the fact that it is more soluble in the soil water than 

 is potassium.
