NOTES TO TABLE IX. (p. 162.) 
[Table IX. is intended to be dr.awn out to the left, free of the book, "2 
as it has reference to the succeeding Tables.] 
1 Far the 16th and succeeding seasons — the sulphate of potass was 
reduced from 600 to 400 lbs. per acre per annum on Plot 1, and from 
300 to 200 lbs. on all the other Plots where it was used ; the sulphate 
of soda from 400 to 200 lbs. on Plot 1, to 100 libs, on all the Plots on 
which 200 lbs. had previously been applied, and from 550 to 336^ lbs. 
(two-thirds the amount) on Plots 12a and 126 ; and the sulphate of 
magnesia from 420 to 280 lbs. (two-thirds the amount) on Plots 14a 
and 146. 
2 Plot 9a — the sulphates of potass, soda, and magnesia, and the 
superphosphate of lime, were applied in the 12th and succeeding 
seasons, but not in the 9th, 10th, and 11th; and the amount of nitrate 
of soda was for the 9th season only 475 lbs. per acre, and for the 10th 
and 11th seasons only 275 lbs. 
3 Plot % — in the 9th season only 475 lbs. of nitrate of soda were 
applied. 
* Common salt — not applied after the 10th season. 
5 Plots 17a and 17b, and 18a and 18b — the manures on these plots 
alternate : that is, Plots 17 were manured with ammonia-salts in the 
9th season ; with the sulphates of potass, soda, and magnesia, and 
superphosphate of lime, in the 10th ; ammonia-salts again in the 
11th; the sulphates of potass, soda, and magnesia, and superphosphate 
of lime, again in the 12th, and so on. Plots 18, on the other hand, 
had the sulphates of potass, soda, and magnesia, and superphosphate 
of lime, in the 9th season ; ammonia-salts in the 10th, and so on, 
alternately.
