Assuming that the forms of organic Nitrogen used p? od . for 



in these brands were as good as in dried blood, it would 



require 1.55 pounds of the organic Nitrogen to furnish +3 

 as much "available" Nitrogen as is contained in 

 1 pound of Nitrate of Soda Nitrogen and 1.43 pounds 

 of the ammonia Nitrogen to furnish as much "avail- 

 able" Nitrogen as is contained in one pound of the 

 Nitrate of Soda Nitrogen. Yet, merely because of 

 commercial conditions, the farmer paid a higher price 

 per pound for his organic Nitrogen than he paid for his 

 Nitrate and his ammonia Nitrogen. Using the same 

 relations that exist in the commercial cost of Nitrogen, 

 the actual prices paid were for organic Nitrogen %6.5% 

 cents per pound, ammonia Nitrogen 23.73 cents and 

 Nitrate Nitrogen 23 cents. At these prices, the Nitro- 

 gen purchased in New Jersey last year cost the farmers 

 about $1,157,400 and in the entire country nearly 

 sixty times as much. 



If, however, the returns from the different forms 

 of Nitrogen were in the same proportion, as indicated 

 in the experiments, which must be admitted to be 

 relatively correct for Nitrate and ammonia, and, as- 

 suming that the organic was as good as that in dried 

 blood, the cost of the "available" Nitrogen in the three 

 forms actually was: 



Per lb. Per lb. 



For organic. .41 cts. While the farmer For organic. ..14.8% 



For ammonia. 34 cts. should have paid, on For ammonia. 16.1% 



For Nitrate . . 23 cts.the basis of availability For Nitrate. . . 23. 



and a saving to the farmers of the State of $383,940 

 would have been effected. If, therefore, instead of 

 buying organic and ammonia Nitrogen, Nitrate of 

 Soda only had been purchased, the same gain in crop 

 from the use of the Nitrogen could have been purchased 

 for $733,460 instead of $1,157,500. 



Assuming that practically the same relations in 

 forms of Nitrogen existed for all the fertilizers made 

 and sold in the whole country this year, the actual cost 

 of the Nitrogen was, in round numbers, $60,000,000, 

 while, on the basis of efficient availability, it should 

 have cost but $43,000,000.
