The plot manured with minerals only ripened a few days 
before the plots manured with ammonia and nitrate of soda. 
No apparent difference was noticeable between the nitrate of 
soda and ammonia plots. 
The barley was threshed out in the field in the beginning of 
November, and the straw weighed at the time of threshing, and 
on the 19th of November the dressed corn was weighed, when 
the results were obtained as shown in the table on page 138. 
It appears from these tabulated results : — 
1. That minerals alone had no effect upon the produce in 
barley. 
2. That ammonia-salts alone produced a better crop than 
nitrate of soda applied Avithout minerals, thus confirming the 
experience of the two preceding years. 
3. That 200 lbs. of ammonia - salts, in conjunction with 
minerals, had a slightly better effect upon barley than an equi- 
valent amount of nitrate of soda and minerals. 
4. That, on the other hand, the larger dressing of nitrate of 
soda on plot 9, in conjunction with minerals, produced a heavier 
crop than minerals and the larger dose (400 lbs.) of ammonia- 
salts on plot 8. 
5. That the small quantity of dung applied to plot 10 did 
not materially raise the produce. In comparison with the yield 
of one of the unmanured plots (plot 1), plot 10, manured with 
3 tons of dung, yielded about 1 bushel less barley ; and in com- 
parison with the barley crop on the second unmanured plot 
(plot 7), the dunged plot No. 10 yielded about 2 bushels more 
barley, 
6. That double the quantity of dung used on plot 10, or 
6 tons applied on plot 11, gave a large increase. 
7. That one of the unmanured plots (plot 1) gave about 6 
bushels more corn, and 2 cwts. 27 lbs. more straw than the 
second unmanured plot (plot 7).
