Cover-crop Plants 



123 



In considering this table, the reader will observe that 

 rape contains the most nitrogen of any of the plants and 

 that turnips are richer in this element than is red clover. 

 This excess is due to the greater tonnage, and it is all 

 taken from the land. In the case of clover and similar 

 plants, some of the nitrogen-content is usually new, since 

 a part may be taken from the air.
