low such crops as corn, potatoes, field roots and 

 beans in the North, and the same crops in the 

 South, wfth the addition of cow peas, soy beans 

 and the non-saccharine sorghums. But it may be 

 sown after other crops when necessary, especially 

 when it is to be pastured. One chief objection to 

 sowing it thus for hay is that the hay will be less 

 free from weeds. 



On upland this crop may be followed with any 

 kind of a crop requiring much nitrogen. No crops 

 can be made to follow it with more advantage, how- 

 ever, than corn and the sorghums, or potatoes. Rape 

 will feed ravenously on the overturned sod, and 

 wheat and the other small grains will also feed 

 similarly. 



On low lands, especially when they partake of the 

 nature of sloughs, the rotation is different. In some in- 

 stances alsike may follow the natural grasses pro- 

 duced by the slough in the drained or undrained 

 form, as the case may be, and may be made to super- 

 sede them without breaking the land, but more com- 

 monly on these it is sown after the natural sod has 

 been broken and has decayed somewhat, by growing 

 on it some such crop as rape or flax. On these 

 lands it is usually grown in long rotations for pas- 

 ture and also for hay, and when the sod is again 

 plowed, it is followed by corn, potatoes, rape, and 

 grains grown for soiling uses, since such land has 

 naturally high adaptation for these. Flax also is a 

 favorite crop to sow in such situations after alsike 

 clover.
