returns, particularly last year, when, owing to excessive rainfall, some-

Table showing Yield of Air-dkt Commercial Hat obtained 

 FOR THE Seasons 1914-15, 1915-16, 1916-17, 1917-18. 



• Note. — The weights given for 1917-18 are for 3 cuts only; 1 cut was not weighed. 



t Note. — I ime was applied in 1913-14 (the initial year) and in 1914-15 only. The other manure.9 

 were applied during these two years, and then every alternate year. 



The table hereunder shows the net profit that has been obtained by 

 the use of the fertilizer top-dressings. The manures were valued as 

 under : — 



Superphosphate 

 Blood manure 

 Bone fertilizer 

 Ground lime 

 Ground limestone 

 Stable manure 



It will be noted that all dressings have given payable returns, and 

 that the least profitable plots have been those treated with insoluble 

 manures. While stable manure has given the highest net profit per 

 acre, it is not always readily obtainable. Superphosphate has given the 

 greatest return for the outlay involved. It has been shown to be an even 

 more valuable stimulant for lucerne than it is for wheat. For an outlay 

 of 1 cwt. of superphosphate per annum, valued at 5s., an average net 

 profit of over £2 per acre has been obtained as a result of top-dressing.
