68 FERTILISERS AS AN AID TO 



lege herd with known records and equal in 

 most respects. One lot was turned on to plot 

 A (unmanured) and the other on to plot B 

 (manured) seven weeks after the application of 

 the fertilisers. After each milking the yield of 

 every cow was weighed and sampled for testing. 



After grazing for twenty weeks the cows were 

 removed and nothing more was done to the plots. 

 Early in May, 1910, cows were again placed upon 

 the plots, similar care being taken as at first, and 

 they were grazed for twenty weeks. 



In May, 1911, the plots were again stocked 

 with cows, the same care in selection being taken 

 as in previous years. Owing to the very dry 

 season it was only possible to graze them for 

 sixteen weeks. Nothing further in the way of 

 manuring or otherwise has been done to either 

 of the plots since the trial commenced. 



The following are the results at the end of the 

 three years* grazing period : 



Gain from fertilisers for three years, 10,369! 

 Ibs., which being reduced to gallons per acre is an 

 increased yield of 251 gallons of milk per 

 statute acre.
