INSPECTION OF COMMERCIAL FERTILIZERS 25 



Mixtures Substantially Complying with Guarantees — Concluded. 



1 Five analyses. In 3 samples (2 analyses) the mineral nitrogen was derived largely from 

 ammonia salts; in 2 samples, largely from nitrate salts; in 1 sample, 3/5 from nitrate salts and 

 2/5 from ammonia salts. One other sample was deficient; see analysis in table of "Mixtures 

 showing a commercial shortage of $1 or more per ton." 



' Five analyses. In 4 samples the mineral nitrogen was derived largely from ammonia salts; 

 in 1 sample, 1/2 from nitrate salts and 1/2 from ammonia salts; Two other samples were deficient; 

 see analyses in table of "Mixtures showing a commercial shortage of $1 or more per ton." 



' Four analyses. In 3 samples the mineral nitrogen was derived largely from ammonia salts; 

 in 1 sample, 3/5 from nitrate salts and 2/5 from ammonia salts. 



* Three analyses. In 2 samples the mineral nitrogen was derived largely from ammonia 

 salts; in 1 sample, largely from nitrate salts. 



' Nitrate salts 7/10, ammonia salts 3/10. 



s The remainder muriate; i.e., sufficient chlorine present to account for this amount of potash. 



' Two analyses. 



8 Largely nitrate salts. 



' In one sample all of the potash was in form of muriate; in one sample, 1/3 was in the form 

 of sulfate. 



1° Three other samples were deficient. See analyses in table of "Mixture showing a com- 

 mercial deficiency of $1 or more per ton." 



'1 Nitrate salts 1/5, ammonia salts 4/5. 



12 Nitrate salts 1/4, ammonia salts 3/4. 



1' Nitrate salts 1/3, ammonia salts 2/3. 



14 Nitrate salts 2/5, ammonia salts 3/5. 



15 The guaranteed composition given on the carton which contained the bottle of solution 

 was Nitrogen 9.88%, Available Phosphoric Acid 14%, Potash 6%, and refers to the Bloomaid 

 fertilizer in solid form, the label stating further that 11/2 ounces were in solution. The capacity 

 of the bottle was 8 ounces, which would make the- actual guarantee of the solution about as follows: 

 Nitrogen 1.85%, Available Phosphoric Acid 2.62%, Potash 1.12%. To avoid misunderstanding 

 future guarantees on this product will refer to the solution and not to the fertilizer chemicals that 

 are used in its manufacture. 



1' Nitrate salts 1/2, ammonia salts 1/2. 

 •' Nitrate salts 4/5, ammonia salts 1/5. 

 1' Nitrate salts 3/5, ammonia salts 2/5.
