The unsettled conditions which have prevailed in the fertilizer trade have un- 

 questionably made it a very trying period for the fertilizer manufacturer who was 

 obliged to provide for his needs several months in advance. This naturallj^ left him 

 with stocks of mixed goods assembled from crude stock products bought several 

 months previously on a high market. The relatively high prices for mixed goods as 

 compared with unmixed fertilizing materials which prevailed at the opening of the 

 spring trade was perhaps not unexpected. Although the earlier purchaser of mixed 

 goods was given the assurance of the manufacturer that he would benefit by any 

 later reduction in prices, nevertheless he was reluctant to buy his usual tonnage, and 

 not unfrequently he turned to unmixed products for his plant food. Prices very 

 favorable to the consumer have prevailed for chemicals and crude stock materials, 

 although, with the exception of acid phosphate, these products have not been par- 

 ticularly featured by the average manufacturer of mixed goods. 



The fertilizer trade values given in the table are somewhat in excess of prices 

 which actually prevailed during the spring. It is but fair, however, to the manu- 

 facturer that the six months' average be adopted, for the reason that much of the 

 stock which went into his fertilizer mixtures was bought during the previous fall or 

 summer. The trade values were figured from the average wholesale quotations for 

 cash of standard crude stock materials in New England, New York and New Jersey 

 markets, plus about 20 per cent, as given in the trade journals for the six months 

 preceding March 1, 1921,

1 Fine bone and tankage refer to particles which will upon agitation pass through a sieve having circular openings 

 ^a of an inch in diameter. Coarse bone and tankage refer to particles which will not pass through the sieve.
