334 Report on the Field and Feeding Experiments at Wohum. 
The ammonia plot 2 ripened three or four days before the 
nitrate of soda plot 3, and yielded a larger produce, both in corn 
and straw, than the latter. 
With the exception of plot 8, manured with minerals and 
400 lbs. of ammonia-salts, and plot 9, dressed with minerals and 
550 lbs. of nitrate of soda, which produced about the same 
amount of corn and straw, the yield of all the other plots was 
very poor. 
It will be borne in mind that, before the experiments on the 
continuous growth of wheat were begun, a crop of wheat, yielding 
25J bushels of dressed corn and 20^ cwts. of straw, was grown 
by the late tenant. The third crop of wheat in succession thus 
was grown in 1878, on very light sandy land, and it was to be 
expected that on such land the wheat-producing powers would 
materially decrease on the unmanured plots. Last year the 
unmanured plot 1 yielded 22i bushels of dressed corn, and the 
second unmanured plot 7, 20^ bushels. In 1878 the produce on 
plot 1 was only 15-f-^ bushels, and on plot 7, 12 bushels. Neither 
mineral manures nor farmyard-manure, it will be seen, had any 
decidedly beneficial effect in 1878, which agrees well with the 
experience of the preceding year. 
It should be mentioned, however, that the dung was applied 
to the land in a long and undecomposed condition, which had 
the effect of making the naturally very light soil still more loose 
and hollow ; a circumstance which, no doubt, in some measure 
may account for the poor yield of wheat on the dunged plots 
10 and 11. 
In order to remedy this defect in this year's experiments, the 
dung of a given composition for the permanent wheat and 
barley experiments was made last autumn, and next season 
(1879) the dung will be applied to the wheat in a short rotten 
state as a top-dressing in spring ; and care will be taken to keep 
the land as firm as possible. 
Compared with last year's results, the produce in 1878 has 
considerably fallen off. Thus in 1877 the largest produce which 
was obtained on plot 8, manured with minerals and 400 lbs. of 
ammonia, amounted to 43-- bushels of corn, and 48^ cwts. of 
straw and chaff. In 1878 the greatest weight of corn was again 
produced on plot 8 ; but it amounted to only 27 bushels of corn. 
The yield of straw on plot 8, in 1878, weighed 42^ cwts, as 
against 48^ cwts. in 1877. The decrease in corn in 1878, it 
thus appears, was more marked than that of straw. The same 
remark applies to all the experimental plots, whether unmanured 
or dressed with various mineral and nitrogenous manures ; they 
all yielded more straw in proportion to corn in 1878 than in the 
preceding season.
