THE CLOVERS 



can be made in them, as is the case with corn. 

 Even when winter kills the plants, a successful 

 fall growth is highly profitable, adding more ni- 

 trogen before winter than red clover seeded at the 

 same time. Where the plants do not winter-kill, 

 they are plowed down for green manure when in 

 bloom in May, or earlier in the spring to save 

 soil moisture and permit early planting, although 

 a good hay for livestock can be made, and the 

 yield is about the same as that of the first crop 

 of red clover. 



In the northern states a large amount of money 

 has been wasted in experimental seedings with 

 crimson clover, and it is only in exceptional cases 

 that it continues to be grown. There is reason 

 to believe that many of these failures were due 

 to lack of soil inoculation. The Pennsylvania 

 experiment station is located in a mountain valley 

 where winters are severe. Crimson clover is 

 under test with other cover crops for an experi- 

 mental orchard, and success with it has increased 

 as the soil has become fully inoculated. This 

 view is supported by the experience of various 

 growers in the north, and while crimson clover 

 can never make the success in a cold climate that 

 it does in Delaware, there is a much wider field
