These figures have been obtained after a long series 

 of years ; beside them we may mention those recom- 

 mended by Coren winder.^

' Mr. Coren-winder obtained those figures by forming a table as follows : — 



As shown in these experiments nitrate of soda, when alone, will 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.
