three, and four year rotations for cotton farms. 

 The legume crops to be used with these rota- 

 tions will vary in different sections and on 

 different soils: 



TWO-YEAR ROTATION 



Bur clover can be seeded on the cotton land 

 from August I5th to October 15th, depending 

 on the latitude. Seed should be sown in 

 the bur. The clover will mature seed in the 

 spring in time to prepare the land for corn. 

 It will not be necessary to reseed this land 

 the following fall. The land for cotton will 

 have to be broken in the spring before the bur 

 clover seeds, but there will usually be enough 

 seed remaining in the soil from the past 

 year to get a good stand of clover after the 

 cotton.
