In order to ensure better utilisation of the nitrate of soda, 

 Stutzer recommends its division into three portions, one 

 half the total being applied in April, one fourth early in 

 June, and the remainder in the middle of July; this is 

 particularly advisable in rainy climates. 



The quantities given by Stutzer will in most cases be 

 sufficient to induce normal grov^th ; but as the amounts of 

 phosphoric acid and potash are larger than those removed 

 by an average hop crop, the ground will gradually become 

 richer in these two substances. 



Fruwirth,^ who rightly advises caution in the use of 

 nitrate of soda, proposes to replace an average dressing of 

 stall manure by — 



120 grams (4J oz.) of nitrate of soda, 

 100 ,, (3 J oz.) of superphosphate, and 

 80 ,, (2| oz.) of sulphate of potash. 



These figures do not differ greatly from those of Stutzer, 

 and in this case also the ground will become richer in phos- 

 phoric acid, and, to a smaller degree, in potash. The quality 

 of the cones is said not to have depreciated under the 

 influence of this dressing, but to have remained about equal 

 to that obtained by the aid of stall manure. 



The reports issued on the results of the experimental 

 manuring of hops with artificials are somewhat divergent, a 

 circumstance not surprising, in view of the different classes 

 of soil on which hops are grown in various localities. Most 

 of these reports are defective in that, as a rule, merely the 

 weight of cones gathered was recorded, leaving more or less 

 unconsidered the influence of the manuring on the quality of 

 the produce.
