Sampling statistics for the year are as follows: 22,895 sacks were sampled, 

 representing 7,718 tons of fertilizer, thus about one ton to every eight that 

 was sold in the state was sampled; 196 towns were visited; 1,956 samples, 

 representing 489 distinct brands, were drawn from stock in the possession of 

 610 agents or owners; 209 other agents were called upon, but no samples 

 were taken for the following reasons — agency discontinued, stocks all sold 

 out, stocks included only those brands of which a sufficient number of samples 

 had already been drawn in that territory.

The mineral forms of nitrogen have continued to decline in cost during the 

 ■past season, the outstanding feature being the great drop in price of nitrate 

 of soda, which amounts to $12.18 per ton, thus making the unit cost of ni- 

 trogen from this source more comparable to that of ammonium sulfate. Even 

 so, the unit cost of nitrogen from the latter salt is still 50 cents under that 

 for the nitrate salt. 



Superphosphate has declined $1.25 per ton from the average price for six 

 months ending March 1, 1931, and 50 cents per ton from the average price 

 for the same period for 1932. 



Some of the organic ammoniates have declined still further in price from 

 the low figures recorded in 1931, and more recent quotations indicate that a 

 further decline in price is not unexpected. Dry ground fish has led in the 

 price decline, being quoted Sept. 26 for $13 under the average quotation for 

 six months ending March 1, 1932, while dried blood has shown a further 

 decline of $1.25 for the same period. Animal tankage and cottonseed meal
