(2). That the low grade goods were the only class which sold 

 on the average at a slightly higher ton cost than during the pre- 

 vious year, 



(3). That the precentage excess of the selling price over the 

 commercial value of plant food in the low grade fertilizers is over 

 2)4, times more than in the high grade goods and about 1^ times 

 more than in the medium grade fertilizers. 



(4). That with a 28.5 percent advance in price over the low 

 grade fertilizer, the high grade furnishes about 91 percent in- 

 crease in commercial plant food value. 



(5). The money difference between the average selling price 

 and the average valuation in the high grade fertilizers is $4.00 

 less than in the low grade goods. It probably costs no more to 

 manufacture a ton of low grade goods than it does a ton of the 

 high grade, besides in the low grade fertilizer opportunities are 

 offered for the use of low grade ammoniates and low grade potash 

 compounds. These facts all emphasize the many advantages to 

 be gained by buying only high grade mixtures. 



Table showing the average composition of the three grades of 

 fertilizer. 



The above table shows: 



(1). That a ton of the average high grade fertilizer furnishes 

 45.6 pounds more nitrogen and 98.4 pounds more actual potash 

 than does a ton of the low grade goods. 



(2). That a ton of the average high grade fertilizer furnishes 

 27 pounds more nitrogen and 53. 4 pounds more potash than does 

 a ton of the medium grade goods. 



(3). That with a 28.5 percent advance in price over the low 

 grade fertilizer, the high grade furnishes about 65 percent increase 

 in available plant food.
