New YorK AGRICULTURAL EXPERIMENT STATION. A413 
Kxample.—In No. 119, the-per cent. of ammonia, as given in the 
guarantee-analysis, is 3 to 4. Hence, 3x.8235—2.47 per cent. 
nitrogen ; 2.47 x 153 cents=38 cents. 
2. Available and insoluble phosphoric acid. 
Use the lower number of the guarantee-analysis and proceed as 
in valuation from Station analysis given above. 
3. Potash. 
If the per cent. of actual potash is given, then proceed as above ~ 
in valuation from Station analysis. If potash is given as sulphate, 
then multiply the per cent. of sulphate by .54, which will give the 
amount of actual potash equivalent to the sulphate. Multiply 
the number thus obtained by five and one-half cents. If the 
potash is given in the form of muriate (chloride), multiply the per 
cent. of muriate (chloride) by .68, and then multiply the result by 
four and one-half cents. 
Example.— A. fertilizer is guaranteed to contain “six to eight 
per cent. of potash as sulphate ;’ 6x.54=3.24 per cent. of actual 
potash ; 3.245} cents=17.8 cents, the value of potash as sul- 
phate in 100 pounds of fertilizer. 
EHxample.— A fertilizer is guaranteed to contain five to seven 
per cent. of potash as muriate (chloride) ; 5x.63=3.15 per cent. 
of actual potash; 3.15x43 cents=14.1 cents, the value of the. 
actual potash as muriate in 100 pounds of fertilizer. 
4, Valuation of one ton. 
Proceed as under valuation from Station analysis. ) 
Example.—A guarantee analysis is as follows: Ammonia 
equals two to three per cent.; available phosphoric acid equals 
ten to twelve per cent. ; insoluble phosphoric acid equals one to 
two per cent.; potash as sulphate equals five to six per cent.
