Simple Rule for Calculating the Approximate Commercial 

 Valuation of a Fertilizer from the Results 

 , OF Analysis. 



Multiply the per cent of nitrogen by three and to the product add 

 the pel" cent of available phosphoric acid and the per cent of potash. 

 The total sum will express in dollars and cents the approximate 

 commercial valuation of one ton (2,000 pounds) of the fertilizer. 



Example. — A fertilizer contains 3.44 per cent of nitrogen, 6.15 

 per cent of available phosphoric acid and 9.89 per cent of potash. 



3.44 (per cent nitrogen) multiplied by three equals $10 32 



6. 15 (per cent available phosphoric acid) equals > 6 15 



9 . 89 (per cent potash) equals 9 89 



Total : $26 36 



LIST OF MANUFACTURERS WHO HAVE FILED STATE- 

 MENTS REQUIRED BY LAW. 



Manufacturers to the number of 184 have filed with this Station 

 the statement required by law. Of these there are 61 whose 

 factories are located outside of New York State. These 184 

 manufacturers put on the market 1,728 different brands. Many 

 of these brands are manufactured for special parties in other 

 states, so that the number of different brands actually sold in this 

 state is short of the total given above. Within the past two 

 years it has become very common to have special goods made for 

 local dealers which have a limited sale in the dealer's immediate 

 locality. This method is becoming more and more common, and, 

 of course, increases largely the number of brands made and sold.
