Table LX.—Relative predominance of Plantago lanceolata. 
Plantcigo lanceolata was found in the samples from 16 plots in 1862, 14 in 1867, 
14 in 1872, and 16 in 1877 ; in 1862 it came first on three plots, second on two, but 
third on none ; in 1867 it came first on four plots, and second on two; in 1872 it did 
not come either first, second, or third on any plots, but in 1877 it was again first on 
two, and second on two. 
It yielded more than 5 per cent, to the produce on four plots in 1862, on three in 
1867, on none in 1872, and on only one in 1877. 
The conditions under which it asserted prominence to the degree shown by the table 
are significant. It so occurred on only six plots : the two unmanured ones, the plot 
unmanured for some years after the application of farmyard manure, the plot with 
superphosphate of lime alone, and the two plots with nitrate of soda without mineral 
manure. Four of the six plots were therefore characterised by extremely restricted 
growth of the herbage in general, and the remaining two (nitrate of soda alone), by 
imperfect development and maturation. 
Even with the nitrate of soda and mineral manure together, the more vigorous growth 
induced in its associates was adverse to this plant. 
With ammonia-salts, both with and without mineral manures, it was very much 
reduced, and in many cases banished—at least to such an extent as not to appear in 
the samples. 
Upon the whole, then, this plant has decreased, or even disappeared entirely, on all 
plots where there was general luxuriance ; and whether from direct action of the 
manure, or from competition, it has suffered much more under the influence of ammonia- 
salts than under that of nitrate of soda. The results of the observations at Chiswick 
(see Jour. Roy. Hort. Soc., vol iii., 1873, p. 144) would seem to show that the action of 
ammonia was directly adverse to the plant, whereas that of nitrate of soda was not so.
