Table showing Average Cash Price and Commercial Plant Food Value per 

 Ton, also Money Difference between Cash Price and Plant Food Value. 



The above table shows : — 



1. That the average ton price of the three grades of fertilizer 

 has been $1.42 less, and the average cost of plant food in a ton 

 66 cents less, than for the previous season. 



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

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

 previous year. 



3. That the percentage excess of the selling price over the 

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

 over two and one-half times more than in the high-grade goods, 

 and about one and three-fourths times more than in the me- 

 dium-grade fertilizers. 



4. That with a 28.5 per cent, advance in price over the low- 

 grade fertilizer, the high-grade furnishes about 91 per cent, 

 increase in commercial plant food value. 



5. That the money difference between the average selling 

 price and the average valuation in the high-grade fertilizers is 

 $4 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 opportuni- 

 ties 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.
