A standard brand of commercial fertilizers was selected Nitrate of 

 and a mixture equal in fertilizing value to 2CO pounds was f oda f r 



. .7 / r TVT~ r r, / SugEF-BeetS 



prepared. T his required 32 pounds of Nitrate of Soda, - 

 25 pounds muriate of potash, and 137 pounds of dissolved 45 

 phosphate rock. The six plots of the experiment received 

 applications as follows : 



Plot i. Nothing. 



Plot 2. 147 pounds mixture plus 24 pounds Nitrate of 

 Soda. 



Plot 3. 147 pounds mixture plus 103 pounds dissolved 

 phosphate rock. 



Plot 4. 147 pounds mixture plus 20 pounds muriate of 

 potash. 



Plot 5. 195 pounds mixture. 



Plot 6. 250 pounds commercial fertilizer. 



It will be seen by the above that Plots 2, 3 and 4 

 received but three-fourths of the mixture as applied to Plot 

 5; the other fourth being supplied by doubling the amount 

 of Nitrogen, phosphoric acid and potash respectively. 



The yields of beets, percentage of sugar, and pounds 

 of sugar per acre are given in the following table :

These figures show decidedly in favor of increasing 

 the Nitrogen content of the sugar-beet fertilizers. Not 

 only is the yield of beets greater, but the percentage of sugar is 

 higher where an excessive amount of Nitrate of Soda is 

 applied. The marked difference in yield of sugar from the 

 home mixed fertilizer over the commercial fertilizer suggests 

 the possibility of Nitrate Nitrogen being superior to the 

 form of Nitrogen found in the commercial fertilizer.
