1923 List. 



The accompanying list of manui'es obtainable in New South Wales, 

 togetlier with their composition, as guaranteed by tlie vendors, is the result 

 of the revision of the list issued in March, 1919. 



The list is published in the interests of the farmers, and it is hoped that it 

 may serve as a guide to those requii'ing any particular class of manure. 



It must be clearly understood that the figures given are not those obtainecJ 

 by analysis of the sample by the Department. They represent the guarantees 

 given by the vendors in accordance with the provisions of the Fertilisers 

 Act. 



Where possible, samples have been taken from bulk by one of the ofSceis 

 of the Department, and only those manures are inserted in the list which have 

 been found on analysis to be up to the guarantee. 



On acc!»unt of the unsettled conditions obtaining at present, the market 

 value of these manures may alter. An attempt has, however, been made to 

 assi'^n a " unit value" to the fertilising ingredients, viz., nitrogen, phosphoric- 

 acid, ani potash, as in pre-w^ar years. 



The recent arrival of consignments of potash salts from Alsace permits of 

 a unit value being assigned to potash. A note dealing with the Krencli 

 potash salts appeared in the Agricultural Gazette last month. 



A word is necessary in explanation of the column giving the " manurial 

 value" of the manures. These figures are calculated from the composition ofi 

 the manures as repres^^nted by analysis, a definite unit- value being assigned 

 to each of the fertilising ingredients. The units on which the values given 

 are computed are as follows : —
