72 CLOVERS 



through smothering, it may with advantage be fol- 

 lowed by crops for which a clean seed bed is spe- 

 cially advantageous, as flax. It may, therefore, be 

 followed with much advantage by wheat, oats or 

 barley, corn and sorghum in all their varieties, flax, 

 potatoes, field roots, vegetables and such small fruits 

 as strawberries. Where wheat is a success it is 

 usually first grown among the small cereal grains 

 after clover, since it is less able to flourish under 

 the conditions which become decreasingly favorable 

 in the years that follow the breaking up of the clo- 

 ver. Whether wheat or flax, corn or potatoes should 

 immediately follow the growing of clover, should 

 be determined in great part by the immediate neces- 

 sity for growing one or the other of these crops, 

 but also to, some extent by the crops that are to fol- 

 low them. 



Clover may follow such crops as require cultiva- 

 tion while they are growing, and of a character that 

 will clean the soil. This means that it may with ad- 

 vantage be miade to follow corn, sorghum, potatoes 

 or field roots. It may also follow the summer fal- 

 low bare, or producing crops for being plowed under 

 where these come into the rotation. Of course, since 

 clover can to a considerable extent supply its own 

 nitrogen, it may be successfully grown on lands 

 that are not clean, and that may not possess high 

 fertility, but when thus sown the nurse crop with 

 which it is usually sown is not likely to succeed well, 

 because of the presence of weeds in it, and from the 

 same cause the quality of the first of the clover is 

 likelv to be much impaired. The conditions of the
