240 Report on the Field and Feeding Experiments at Wohurn. 
of soda in conjunction with minerals, 41*1 and 40 bushels were 
obtained respectively, the yields in 1884, when no nitrogenous 
manures were applied, being 32-5 and 21 '9 bushels. On the 
other hand, the plots which last year gave 48 8 and 51 bushels 
when manured with minerals and 400 lbs. ammonia-salts per 
acre in the first case, and minerals and 550 lbs. nitrate of 
soda in the second, now, on the omission of the nitrogenous 
manures for this single year, yielded only 24" 7 and 18 bushels. 
It will be noticed that the difference of produce of corn as 
between ammonia-salts and nitrate of soda has this year been 
practically nothing ; but there has been a considerably larger 
yield of straw with the nitrate, 200 lbs. of ammonia-salts per 
acre giving 31*2 bushels of corn and 25 cwts. 2 qrs. 10 lbs. of straw, 
while 275 lbs. nitrate soda per acre gave 28*1 bushels of corn 
only, but as much as 28 cwts. 0 qr. 21 lbs. of straw. The double 
quantities, in conjunction with minerals, gave, in the case of 
ammonia-salts, 41*1 bushels of corn, with 45 cwts. 2 qrs. 14 lbs. 
of straw ; in the case of nitrate of soda, 40 bushels of corn and 
53 cwts. 0 qr. 20 lbs. of straw. The weight per bushel of the 
corn was much the same in either case. Where farmyard 
manure was applied at the rate of 4 tons per acre for the ninth 
successive year the yield was 25 bushels, or 4 bushels only above 
the unmanured plots ; applied at the rate of 8 tons per acre it 
gave 31*8 bushels, against 38 bushels in 1884. Where farm- 
yard manure had been given each year up to 1882, and omitted 
since then, only 19'3 and 20 5 bushels were produced, or rather 
less than on the unmanured plots.

The land was grubbed up on August 25th, and afterwards 
ploughed. The dung for Plots 10 B and 11b was made by four 
bullocks, which consumed the same amounts and kinds of food 
as those making the dung for the permanent wheat. The 
weights were as follows : — »
