Food for while the soil without Nitrate gave a crop of only ^6 bushels. 

 ^" ^ Top-dressings for oats should average lOO pounds to the acre. 

 It should always be applied so?ne ten days after the young 

 plants have broken ground. 



Barley. 



In an experiment at Woburn, made for the Royal Agri- 

 cultural Society of England, by the late Dr. Voelcker, the 

 following results were obtained: 



Mineral manures and sulphate ammonia 36-75 bushels per acre. 



Nitrate 275 lbs. and minerals 42.50 bushels per acre. 



Gain for Nitrate, 16 per cent. 



The ammonia salt and the Nitrate used contained the 

 same amount of ammoniate plant food. Compared with 

 cotton-seed meal, 124 pounds of Nitrate of Soda gave 49.5 

 bushels barley per acre as compared to 37 bushels from 

 1,000 pounds cotton-seed meal applied the previous year. 

 Gain for Nitrate 33.7 per acre. 



Mangolds. 



Nitrate of Soda pays well for roots if applied at the rate 

 of from 150 to 200 pounds per acre. Use in two applica- 

 tions about ten days apart, the first not earlier than July. 

 The Essex Agricultural Society found by experiment that 12 

 tons of farmyard manure and 300 pounds superphosphate 

 gave a crof of nearly ten and one-half tons per acre, but 



when 200 pounds of Nitrate of Soda were 

 Formulas and ^^^^^^ ^^^ ^j^j^ ^^^ increased to over 15 

 Jjirections. tons. The season was very unfavorable. 



Three hundred pounds per acre of Nitrate is recommended. 



Turnips and Swedes. 



Nitrate is applied for this crop quite in the same manner 

 as for mangolds. Dr. Macadam reported to the Arbroath 

 Farmers' Club a gain of 37 per cent, in yield from the use of 

 336 pounds of Nitrate of Soda per acre. 



An experiment conducted by Dr. Munro, of Downtown 

 T d Y* Id Agricultural College, Salisbury, gave a 



return of nearly twenty and one-half tons 

 per acre, from an application of 600 pounds of Nitrate per 

 acre, supplemented by phosphoric acid and potash. The
