COVER CROPS

MAMMOTH CLOVER. 



Although this legume stands low temperatures 

 with less success than several other varieties, the 

 enormous growth of coarse humus making material 

 is valuable, and the roots thoroughly pulverize the 

 soil. 



PEANUTS. 



This legume is almost as useful as an orchard 

 cover crop as it is valuable for direct profit. Of the 

 many varieties the Spanish is adapted to a wider 

 range of soil and conditions than any other. 1 ' This 

 variety has been observed to make a good growth 

 and give profitable returns wherever the cow pea 

 can be grown with success.' 9 (U. S. Bull., 227.) 



RED CLOVER. 



1 ' The renovating character of a crop of red clover 

 is well known, and even when only the stubble and 

 roots are the source of the additions made to the 

 soil the improvement which follows is very marked. ' 9 

 (Penn. Bull., 102.) It is destroyed by hot weather 

 and requires about six or seven months to make 

 a valuable top growth. 



SOY BEANS. 



"This plant resembles the cow pea in many of 

 its characteristics, namely, that it should not be 

 seeded until the soil is warm." (Penn. Bull., 102.)
