By growing legume crops in the summer, 

 turning them under in the fall, and follow- 

 ing with a crop of oats, rye, crimson or 

 bur clover as a winter cover crop, the 

 land will be fully protected throughout 

 the year, and if all these crops are turned

 restored. After one or two years of this 

 treatment the land may be turned over to 

 the regular crops of cotton and corn. Of 

 course, this is not specially applicable to 

 soils that are already in fairly good condi- 

 tion. 



Crop Rotations. Rotation of crops is the 

 safest and surest way of maintaining soil 

 fertility. On every farm a systematic crop 

 rotation should be adopted. This rotation 

 will have to be planned to suit the condi- 

 tions and the location of the farm. What 

 would be good for one farm might not 

 be the best for another, even in the same 

 neighborhood. A few suggestive rotations 

 are given, so that the farmer may have an 

 idea of what is meant by systematic crop 

 rotation. 



Following are suggested outlines of two,
