Nitrate of Attention is called in the following table to the effect

as a fertilizer for sugar-beets. 



The yield in every case was in favor of Nitrate of Soda, 

 while the varying per cents of sugar leave that feature of 

 the question still very inconclusive. 



Comparing plots nine and ten in table one, page 95, 

 we find that Nitrate of Soda produced 4,200 more pounds 

 of beets per acre, which were 1.76 per cent richer in sugar, 

 with a material increase in the co-efficient of purity. 



In connection with the College Farm soil test experi- 

 ment a comparison of ammonia and Nitrate Nitrogen was 

 made. The soil was medium loam and of uniform charac- 

 ter, dissolved phosphate rock and muriate of potash applied 

 in like quantities in each case.

Michigan Experiments on Sugar-Beets in 1901. 



(Extract from Michigan Bulletin 197, 



Issued 1902.) 



A field was planned to test the effect of excessive 

 amounts of each of the various fertilizing elements in 

 comparison with normal applications in the form of com- 

 mercial and home mixed fertilizers.
