In each series the manure is applied to one plot in 1904 and each successive fourth 

 year, to another plot in 1905 and each successive fourth year, to a third plot in 1906 and 

 each successive fourth year, and to a fourth plot in 1907 and each successive fourth year. 

 All the plots in the Series A to E, which deal with Nitrogenous Manures, receive, as 

 necessary, equal amounts of Phosphates and Potash. Similarly, all the plots in the 

 Series F, G, H, dealing with Phosphatic Manures, receive equal dressings of Nitrogenous 

 or Potassic Manures as required. 



(1) In 1912 only 10 tons 8 cwt. per acre of ordinary and cake-fed Dung respectively 

 was applied, instead of 16 tons as in previous years. 



(2) In 1908 and since, the Nitrogenous Manures applied to the plots of Series C, D, and 

 E have been as follows — 



Series C. Shoddy, 957 lb. = 50 lb. N. peracre. 



„ D. Peruvian Guano, 777 lb. = 50 lb. N. 

 „ E. Rape Cake, 1036 lb. = 50 lb. N. 



Check plots receiving in Series A to E no Nitrogen throughout, 

 Series F to H, no Phosphates throughout.
