252 STATE BOARD OF AGRICULTURE. 



It is the desire of this department to make the inspection as complete 

 as possible, and any information to further this end from dealer or con- 

 sumer will be greatly appreciated. In all cases of failure to find a 

 brand on the market, the analysis was made on the manufacturer's 

 sample as indicated in the tables of analyses. 



RESULTS OF INSPECTION. 



A study of the tables of analyses shows that, of the 234 samples 

 analyzed, representing 208 brands, 54 (23%) are below guarantee* in 

 one or more constituents. Twenty-six (11%) are below guarantee in 

 nitrogen, 5 (2.1%) are below guarantee in available phosphoric acid, 

 2 (0.9%) are below guarantee in total phosphoric acid and 2G (11%) 

 are beloAv guarantee in potash. Three (1.3%) are below guarantee in 

 nitrogen and potash, 2 (0.9%) in nitrogen and available phosphoric 

 acid. 



While there are, as stated above, 54 samples falling below guarantee 

 in one or more constituents, there are, however, only 10 (4.3%) that 

 are more, than 75 cents per ton below their guaranteed commercial 

 value. That is, the shortage in one constituent is compensated by an 

 excess of the guarantees in the other constituents. This is a very satis- 

 factory showing. 



SCHEDULE OF TRADE VALUES. 



In accordance with the custom adopted and followed in previous 

 years, the following schedule of prices for determining the commercial 

 valuation of a fertilizer is published : 



Nitrogen ISV^c. per pound 



Potash soluble in water 4,8c. '' " 



Available phosphoric acid 5c. *' '' 



Total phosphoric acid in bone 4e. " " 



Insoluble phos})horic acid in fertilizers 



containing nitrogen 2c. " " 



In fertilizers containing no nitrogen no value is given to insoluble 

 pliosi)lioric acid. Tlie valuation of a fertilizer is determined as follows: 

 Tlie percentage or pounds per hundred of each ingredient (nitrogen, 

 available phosphoric acid, insoluble phos})horic acid and potash) is mal- 

 tiplicd by 20, giving the number of i)ounds of each ingredient in a ton. 

 'i'liese figures are then multiplied by their respective pound prices. 



In the last column of the table of analyses headed ''Valuation" is 

 given the commercial valuation of the samples as guaranteed and as 

 found based upon the prices quoted above. 



COMMERCIAL VALUATIONS. 



In calculating the valuations we have assumed that the sources of the 

 various ingredients have been the same in all cases, which of course is 

 not true and also unfair to the manufacturer using only high grade 

 goods, as it places the manufacturer who uses low grade materials on 

 the same level. 



*A shortage of more than 0.10 par cent of nitrogen or more than 0.20 per cent of available phos- 

 phoric or potash is considered below guarantee.
