Report on the Fidel and Feeding Experiments at Woharn. 121 
A glance at the preceding tabulated results, amongst other 
particulars, shows : 
1. That minerals alone had no effect upon the produce in 
barley. 
2. That nitrate of soda alone produced a better crop than 
ammonia-salts without minerals. 
In the two preceding seasons the reverse was the case, and 
ammonia-salts alone yielded better crops than nitrate of soda 
without minerals. 
3. That, on the other hand, the ammonia-salts and minerals 
on plot 5 produced rather more corn, but considerably less straw, 
than the same quantity of minerals and nitrate of soda on plot 6. 
4. That the same minerals, with double the quantity of 
ammonia-salts which was used on plot 5, produced rather less 
corn but more straw on plot 8, than the smaller quantity of 
ammonia-salts on plot 5. 
5. That the minerals and double quantity of nitrate of soda 
on plot 9 actually produced less corn but considerably more 
straw than half the amount of nitrate of soda on plot G. 
6. That the small quantity of dung applied to plot 10 gave a 
satisfactory increase. 
7. That double the quantity of dung used on plot 10 produced 
a large increase. 
8. That the second unmanured plot (7) yielded 11^ bushels 
less corn and 4 cwts. 1 qr. 13 lbs. less straw than the unmanured 
plot 1. 
This is the fourth season in which the unmanured plot (1) 
produced more barley than the second unmanured plot (7), 
which clearly shows that the land on which plot 1 is situated 
is in a higher agricultural condition than the land on plot 7. 
In comparison with the produce of the eleven experimental 
plots in 1879, all the plots yielded much better crops in 1880. 
The dung plot (11) more especially yielded a very good crop 
considering the bad season of 1880. It will be seen that plot 11 
produced 44 bushels of barley, weighing 52^ lbs. per bushel, or 
two bushels more than twice the number of bushels which the 
second unmanured plot (7) yielded. 
It is worthy of special notice that the weight per bushel was 
heavier on nearly all the experimental barley plots than on the 
corresponding wheat plots. 
The land of the experimental field at Woburn is evidently 
better adapted for the growth of barley than for wheat, and even 
in an indifferent season like that of 1880 yielded good barley 
crops. In a season like the last it is further noticeable that an 
excess of ammonia-salts or nitrate of soda, although both were 
used in conjunction with minerals, actually reduced the yield 
in corn in comparison with the produce of the plots upon which
