 two or three doses, applied in intervals of about ten days. 



Mangolds. 



Nitrate of Soda pays very well on stock roots, and the 

 best application is from i 50 to 200 pounds per acre, applied 

 in two doses about ten days apart, the first dose not earlier 

 than July. The Essex Agricultural Society found by ex- 

 periment that while 12 tons of farmyard manure and 300 

 pounds superphosphate gave a crop of nearly ten and one- 

 half tons per acre, when 200 pounds of Nitrate of Soda were

ravorable. Ur. Uyer suggests 400 pounds 



of Nitrate on soils well run-down, or 3C0 pounds if 10 to 



12 tons of manure have been used ; 100 pounds should be 



sown with the seed, 100 pounds top-dressed after singling, 



100 pounds top-dressed a month or six weeks later, and at 



discretion 25 pounds per month for another period. 



Turnips and Swedes. 



Nitrate is used 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 

 Nitrate, 336 pounds per acre. 



Grass. 



Experiments on grass at the Royal Agricultural College, 

 Cirencester, gave a return of nearly 3 1 cwt. hay from the 

 use of acid phosphate alone and 41.75 cwt. when 280 

 pounds of Nitrate of Soda were used. During March or 

 early in April is the best time to apply Nitrate to grass 

 lands. 



Potatoes. 



A successful grower in England recommends 150 

 pounds of Nitrate per acre, and 250 pounds of acid phos- 

 phate (potash not being supposed necessary in England), 

 sown just before seeding, to be followed by a top-dressing 

 of 100 pounds of Nitrate when the plants are well under
