CHAPTER XII. 



SUCCESSION IN SOILING CROPS. 



It will be the aim in this chapter to designate 

 the various crops that may be grown as soiling food 

 in one season and also the succession in which they 

 may be grown. The task is not easy because of the 

 great difference in the climatic and soil conditions in 

 the various states of the Union and in the provinces 

 of Canada. The only way in which such a designa- 

 tion of soiling crops can be made that will be even 

 approximately correct, is to divide these states and 

 provinces into groups, and then to name the suc- 

 cession in the soiling crops that can be most profit- 

 ably grown in each. This division or grouping of 

 states and provinces, will of necessity have to be 

 based upon similarity in the soil and climatic con- 

 ditions peculiar to each. When those states and 

 provinces have been thus grouped, the succession 

 fixed upon can only serve as a general guide, be- 

 cause of the frequency of variations in soils in 

 states that lie contiguous and also in different parts 

 of the same state. 



In nearly all parts of the United States and 

 Canada, a succession of soiling crops can be grown 

 which will furnish green food from spring until the 

 closing in of winter. The season for growing 

 these crops will of course vary with the differences 

 in latitude and also in altitude. Along the northerly
