236 SOILING CROPS AND THE SILO. 



clover, peas and oats or peas and vetches, corn, sor- 

 ghum, millet, rape, field roots and cabbage. Some 

 of these crops could be grown so as to be in season 

 at successive intervals : Alfalfa and rape are of this 

 class, others are in season simultaneously, as for 

 instance peas and oats, mammoth and alsike clover. 

 The principal soiling crops in a more restricted 

 succession would contain, peas and oats, or vetches 

 and oats, corn or sorghum, and rape or field roots. 

 Where crimson clover can be grown it will be ready 

 for feeding next after winter rye. 



Succession in Section No. 2. The medium 

 red, mammoth and alsike varieties of clover grow 

 well in nearly all parts of states included in Section 

 No. 2, but not in the province of Manitoba. Crim- 

 son clover only succeeds in the more southerly areas 

 of the same, and even in these it is not absolutely 

 reliable. Winter rye, mixed grains, millet, rape, 

 cabbage and field roots grow vigorously, but not 

 with an equal vigor in all the area included. The 

 same is true of corn and sorghum, although these 

 grow much better southward than northward. 

 Peas and vetches grow fairly well but better north- 

 ward than southward. The cowpea and the soy 

 bean in some of their varieties grow nicely in the 

 southern part of Indiana, Illinois and Iowa, but 

 not so well farther north. Alfalfa grows only in 

 sectional areas. It is evident, therefore, that the suc- 

 cession in the northern third of this section would not 

 be the same as in the southern third. In the former 

 the order in which the leading soiling crops would be 

 ready would be as follows : 



Winter rye, peas and oats or peas and vetches,
