In the above table it is noticed that the average 

 yield of hay following cowpeas and soy ])eans is 877 

 and 858 pounds greater respectively than when it fol- 

 lows corn. When the hay was valued at $15.00 a ton, 

 the fertilizing effect of the cowpeas was $6.56 per acre, 

 and of soy beans $6.43. 



In 190C) an experiment was conducted to secure data 

 on the fertilizing eft'ect of corn, cowpeas, and soy beans 

 on a succeeding winter oat crop. The increase in yield 

 of oats due to cow|)eas, even where the seed had been 

 picked, was about 300 per cent over the yield from the 

 corn land. The increase in oats due to soy beans, which 

 were gathered in such a way as to leave only the stub- 

 ble, was 173 per cent over the yield from the corn land. 



The Ohio Experiment Station found that the average 

 yield of wheat following soy beans was 10.3 bushels 

 greater than that following corn.*
