NOTES TO APPENDIX-TABLE I. (p. 1). 
(Appendix-Table I. is intended to be drawn out to the left, free of the book, as it 
has reference to the succeeding Tables.) 
(') 1858 and previously. — Sulphate of Potash, 600 lbs. per acre per annum on 
Plot 1, and 300 lbs. on all plots which now receive 200 lb.s. per acre. Sulphate 
of Sodii, 400 lbs. ou Plot 1, and 200 lbs. on all plots where 100 lbs. is now applied. 
Plots 12a and 12b, Sulphate of Soda 550 lbs. per acre per annum. Plots 14a 
and 14b, Sulphate of Magnesia 420 lbs. per acre per annum. 
(0 Plot 9a.— 1852, Nitrate of Soda 475 lbs. per acre ; 1853 and 1854, 275 lbs. 
only. No minerals were applied to this plot in either of these 3 years. 
Plot 9b.— 475 lbs. Nitrate of Soda in 1852. 
(') Plots 15a and 15b.— 1873 and since, Superphosphate made with 150 lbs. 
Sulphuric Acid. For the crop of 1873 and since, Eape-cake has been omitted on 
15b; and instead of the 400 lbs. Sulpliate of Ammonia on 15a, and 300 lbs. 
Sulphate of Ammonia on 15b, each plot has received 200 lbs. Sulphate, and 
200 lbs. Muriate of Ammonia, in addition to the mineral manures. 
, Plots 16a and 16b.— Unmanured for the crop of 1805 and since. 
(^) Plots 17a and 17b, and 18a and 18b. — On these plots the maniures have 
alternated each j'ear since 1852; that is. Ammonia-sails ou Plots 17a and 17b, 
and the mixed mineral manure on Plots 18a and 18b in one year; mineral 
manure on Plots 17a and 17b, and Ammonia-salts on Plots 18a and 18b in the 
next year, and so on. 
(') Plot 19. — 1879-82 inclusive, Eape-cake alone, 1700 lbs. per acre per 
annum ; 1883, increased to 1889 lbs. (containing Nitrogen = to 400 lbs. Ammonia- 
salts). 
(*) Plot 20. — In 1880 this plot was divided, and since one portion f20-l) has 
been manured with Eape-cake alone, as Plot 19, the other portion (20-2) being 
left unmanured as before. 
Application of Cut Wheat Straw. — For the crops of 1868 to 1879 inclusive, cut 
straw (that produced on the respective plots in the previous season), was applied 
on the " A ' portions of Plots 5, 6, 7, 8, 11, 12, 13, 14, and 17 (or 18) ; also for the 
crop of 1874, and each succeeding crop to 1879 inclusive, the straw of the previous 
season was cut up and applied to the "a" portion ot Plot 15. For the crop of 
1880, and since, tlie return of the straw has been discontinued. 
Spring and Autumn Sowinr) of Manures. — From the commencement of the 
experiments in 1843-4 up to 1876-7 inclusive, the mineral manures, the 
ammonia-salts, and rape-cake, &c., were sown in the autumn before the seed ; 
excepting in 1845, when, owing to the wet autumn and winter, all the manures 
were spring-sown ; and tor the crops of 1873, '4, '5, '6, and '7, the ammonia-salts 
applied to Plots 15a and 1 5b were top-dressed in tlie spring. Nitrate of Soda 
has, however, always been sown in the spring. But, in consequence of the 
ascertained great loss of the nitrogen of the manures by drainage, especially in 
wet winters, it was decided to apjily only the mineral manures (and farmyard- 
manure) in tlie autumn, and the ammonia- salts, as well as the nitrate, in the 
spring ; excepting on Plots 15a and 15u, where, for comparison, the ammonia-salts 
are sown iu the autumn. This plan was adopted for the crops of 1878 to 1883 
inclusive.
