THE SUGAR BEET. 



These figures have been obtained after a long series 

 of years ; beside them we may mention those recom- 

 mended by Corenwinder.^ 



Nitrate of soda . 

 Nitrate of potassa 

 Superphosphate .

' Mr. Corenwinder obtained these figures by forming a table as follows : — 



As shown in these experiments nitrate of soda, when alone, wiU yield slightly- 

 superior results to those it did when combined with chloride of potassium and 

 phosphate, hence the addition of the latter is of no use. With a given quan- 

 tity of superphosphate the yield is much increased and the quality of the root 

 also, and this will increase in a poor soil. 



In experiment (8) 200 kilog. of nitrate of potassa have been left out, and with 

 the same amount of superphosphate the better results were obtained.
