of nitrates, bicarbonates, sulfates, and silica in dra'nage water from the 

 bare and the cropped tanks for the five-years period, is shown in table 25:

AND FROM Unplanted Tanks 



Effect of lime on removal of calcium 



Treating this soil with burnt lime at the rate of 3000 pounds per acre 

 did not result in increasing the quantity of calcium in the drainage water 

 or in the ash of the crops produced. A statement of the calcium removed 

 in crops and in drainage water from the hmed and the unhmed tanks 

 is contained in table 26: 



TABLE 26. Average Annual Removal of Calcium from Limed and from Unlimed 



Tanks 



(In pounds per acre) 



The application of Ume was not sufficient to meet the Hme requirement 

 of the whole body of soil. If, therefore, any more calcium was dissolved 

 from the upper soil in the hmed tanks than in the unhmed, it was evidently 

 absorbed by the still unsatisfied soil below, and the final result was about 

 the same in both cases.
