 - Nitrate of Soda fed to growing crops at the right time 

 repays its cost many times over. 



If there is no Nitrate present, the plant must wait 

 until the Nitrogen in the cotton-seed meal becomes 

 nitrated, which, in cool, damp soil takes a considerable 

 time. Thus the plant, in its most critical stage, is held 

 back and checked in its growth, from which it never fully 

 recovers. On the other hand, if a small quantity of 

 Nitrate is used, the plant can take it up at once and 

 get a good strong start by the time the cotton-seed 

 meal is converted into the Nitrate form, the only form 

 that can be used by the plant. 



Profitable Use of Nitrate of Soda on Cotton. 



In forty tests in 1904 at the South Carolina 

 Experiment Station, where Nitrate of Soda was used 

 at the rate of 200 pounds to the acre, the yield was 

 1,740 pounds of seed cotton per acre, compared with 

 an average yield of 868 pounds per acre for thirty-four 

 plots on which various fertilizers were used, and an 

 average yield of 425 pounds per acre for six unfertil- 

 ized plots. 



The table on page 77 shows the average yearly 

 yields per acre for the four years during which the 

 experiments were carried on, together with the profits 

 shown by the use of various fertilizers, is condensed 

 from similar tables on pages 21, 22 and 23 of Bulletin 

 145 of the South Carolina Experiment Station, Clem- 

 son College, S. C., and from a report for 1910 from 

 the same station. 



Doubling the Cotton Crop a Problem of 

 Sane Fertilizing. 



Should the world's cotton spinning demands re- 

 quire the doubling of the American cotton crop within 

 the next five or ten years, along what lines of develop- 

 ment in means and methods could it be most economi- 

 cally accomplished? 



This is a question which some consider a practical 

 proposition. They look forward to an era, after the
