I have already told of the increase in 1910 of the nine tons put on in 

 1909 on twenty acres, 15 bushels per acre increase of oats; and of clover 

 from the first two tons put on in 1906, clover more than doubled in 1910. 



In 1911 the field that was in phosphated oats in 1910 gave an increased 

 yield of 5 bushels of corn per acre. 



In 1912 thirty-six acres of phosphated corn yielded 71% bushels per 

 acre and the balance of corn on the farm 53% bushels per acre, giving an 

 increase of 18 bushels. 



Oats on ten acres of phosphated ground yielded 78 bushels, balance 

 of oats 53 bushels, an increase of 25 bushels per acre. 



In 1913 the same thirty-six acres was put back into corn and gave an 

 increase of 6 bushels of corn per acre above balance of corn on the farm. 



In 1913, I had sixty acres of clover, twenty acres of which was phos- 

 phated with the nine tons in 1909, and forty acres of clover in the same 

 field. County Advisor Bishop held a demonstration in this field June 17, 

 1913. Seventy automobiles were lined up and over three hundred people 

 were present. Everyone was of the opinion that the clover was more than 

 doubled. 



In 1914 oats on the thirty-six acres gave an increase of 9 bushels per 

 acre more than the balance of the farm. 



Clover more than doubled on a sixty acre field and was said to be the 

 finest large field of clover in the county. I failed to get a stand of clover 

 on this field in 1907, 1909 and 1911, and I also would have failed in 1913 

 if the oats had not been exceptionally thin. Rock phosphate was applied 

 during the fall of 1913, and as stated, clover was doubled in 1914. In 

 the fall of 1914 I had gone over the balance of the farm and now the 

 entire 320 acres had been covered with one ton per acre of rock phos- 

 phate and an extra forty tons had been put on the little knolls and ridges. 



Late in the fall of 1916 I bought an adjoining eighty acre farm and in 

 1917 it was all put into corn, yielding 45 bushels per acre and the corn 

 on the home farm, ninety-two acres, made 63 bushels per acre, 18 bushels 

 per acre increase in favor of the phosphate. 



The following tables give a comparison for a period of years:
