COVER CROPS

" It is destined to become a very important agricul- 

 tural product in many sections of the United States, 

 both, as a grain and forage crop." (U. S. Bull., 

 289.) "Its great value as a crop has been clearly 

 demonstrated." (U. S. Bull., 58.) "Soy beans 

 are preferred to cow peas by an increasing number 

 of farmers in the South." (U. S. Bull, 278.) 



SWEET CLOVER. 



' ' Owing to the ability of sweet clover to grow in 

 the poorest of soils, it will probably be found of 

 high value in increasing their fertility. The seed 

 should be planted very early in the spring." (U. 

 S. Bull.. 278.) It is a biennial. 



TANGIER PEAS. 



This beautiful plant is rapidly increasing in 

 favor as a cover crop among the citrus fruit orch- 

 ards of the Pacific Coast. It is of rapid growth, 

 choking weeds effectively, and makes a large yield 

 of stalk, which decays easily, while the amount of 

 nitrogen left in the ground indicates a high fertiliz- 

 ing value. 



VELVET BEANS. 



This legume is in some respects the most valuable 

 of cover crops. Aside from a viny habit which ren- 

 ders it difficult to plow under, it compares favor- 

 ably with the best varieties of cow peas, even ex- 

 ceeding them in deposits of nitrogen.
