It is of interest to compare the unit values for fertilizing substances in 

 the various States of Australasia. The table below, prepared by the 

 Australasian Association of official Agricultural Chemists (1906 confer- 

 ence), shows that the values are, on the average, practically in favour of 

 Victoria, while in the case of superphosphate the table indicates that 

 Victorian agriculturists possess a decided advantage over those of the 

 other States and New Zealand. In New Zealand a ton of superphosphate 

 guaranteed to contain 20 per cent, water soluble phosphoric acid, and 

 \\ per cent, insoluble would be valued at ;^6 5s. 3d., as against a value of 

 ;^4 IIS. 6d. in Victoria. The same manure would be valued at ;^5 3s. 

 loW. in New South Wales. 



Table I. 



COMPARATIVE UNIT VALUES FOR MANURES OF AUSTRALASIA, I906. 



The values fixed for fertilizing substances in the United States 

 (Massachusetts, Connecticut, Rhode Island, Maine, Vermont, and New 

 Jersey Stations Conference)* are given below Table II. They are in- 

 structive, and indicate that the agriculturists of Victoria are quite as well 

 supplied with phosphatic manures in regard to trade prices, as the agricul- 

 turists of the above American States. For nitrogenous manures, the 

 American \alue is much higher than in Victoria. In California, as shown 

 in Table II., the cost of manures of almost all classes is higher than in 

 Victoria, the cost of nitrogenous fertilizers being half as much again as 

 in this State.
