benefit to crops to be derived from applications of sulfur. It should be 

 noted, however, that while sulfate of potash was the only commercial 

 fertilizer appUed to any of the lysimeters, all received an appUcation 

 of 10 tons of farm manure at the beginning of the experiment and again

in 1914. Sulfur was determined only in the manure applied in 1914.' 

 Assuming the two applications to be equal, they would contain about 62 

 pounds of sulfur per acre. It is quite evident that, at the rate at which 

 sulfur is carried off b}^ the drainage water from these tanks, there is 

 Ukely to be a deficiency in the soil in a measureable length of time. 



Effect of lime on removal of sulfur 



The application of lime was accompanied by an increase in the quantity 

 of sulfm' in the drainage water, as may be seen from table 59:
