indicating in what portion of the Stater the largest 

 amount of money is expended for commercial fertilizers: 



Long Island (Counties of Nassau, Queens and 



Suffolk) $1,241,280 



Monroe County 214,000 



Erie County 186,370 



Cayuga County 131,260 



Oneida County 112,630 



Onondaga, Ontario, Wayne, Ulster, Chautau- 



qua, each from $102,000 to 110,000 



These twelve counties use about one-half of the 

 commercial fertilizers used in the entire State. 



Composition of Fertilizers in Different Classes. 



If we compare our four different classes of com- 

 plete fertilizers in respect to the average amounts of 

 Nitrogen, available phosphoric acid and potash con- 

 tained in them, we have the following table : 



Composition of Different Grades of Fertilizers. 



IN 100 POUNDS OF FERTILIZER.. 



In the fourth column, under the heading "pounds 

 of total plant-food," we give the sum of the Nitrogen, 

 available phosphoric acid and potash. We notice the 

 following points in connection with this table: 



1. The percentage of phosphoric acid does not 

 vary greatly in the different classes of fertilizers. 



2. The percentage of Nitrogen and of potash in- 

 creases in the higher grades. 



3. The total amount of plant-food in 100 pounds 

 of fertilizer increases in the higher grades, this increase 

 being due to increase of Nitrogen and potash.
