266 CLOVERS 



in the strict sense of the term; and yet, because of 

 the extent to which it grows when it has once ob- 

 tained a footing in soils, it is more or less fre- 

 quent in all rotations in which grass or clover is 

 one of the factors. As it usually comes into the 

 grass pastures, when these have become established, 

 it will occupy about the same place as blue grass 

 in rotations; that is to say, whatever would be 

 proper to sow after the blue grass would be proper 

 to sow after this plant; since the two usually unite 

 in making" the same sod. It will, therefore, be in 

 order to follow this plant with corn to feed upon 

 the nitrogen furnished by the clover. The same 

 will be true of any small cereal that has special 

 adaptation for being grown on overturned sod, as 

 for instance, flax or oats, or of any crop that revels 

 in the decay of vegetable matter, more especially in 

 the early stages of such decay, as, for instance, pota- 

 toes and rape. When white clover is sown on land 

 that is cultivated, though only sown as a factor 

 in a pasture crop, as with all other clovers it may 

 best be sown on land that is clean; that is, on land 

 on which the preceding crop has been cultivated to 

 the extent of securing a clean surface on the same. 

 If, however, this crop must needs be sown on land 

 that has not been thus cleaned, its great inherent 

 hardihood will enable it to establish itself where 

 some clovers and grasses would fail. 



It is common to sow white clover on land from 

 which the forest has recently been removed, also 

 on natural prairie, where it has not previously 

 grown. In these instances it simply follows the
