(5) Effect of fertilizers on money value of crop. — With the 

 use of 500 pounds of fertilizer the money value of the crop in- 

 creased in 14 out of 17 cases, the increase varying from 32 cents 

 to $23.15 an acre and averaging $7.26. The use of 750 pounds, 

 as compared with 500 pounds of fertilizer, increased the money 

 value of the crop in 11 out of 17 cases, the amount of increase 

 varying from 30 cents to $13.76 and averaging $2.61. The use 

 of 750 pounds of fertilizer, as compared with no fertilizer, in- 

 creased the value of the crop in 15 out of 17 cases, the increase 

 varying from 65 cents to $23.94 and averaging $9.87. 



The use of 500 pounds of fertilizer increased the average value 

 of the crop enough to pay for the fertilizer used and leave $1.26 

 over. The use of 750 pounds of fertilizer increased the average 

 value of the crop $9.87 or enough to pay for the fertilizer used 

 and 87 cents more. Hence, the use of 750 pounds of fertilizer 

 was attended with less profit than the use of 500 pounds.
