172 KNAPP METHOD OF GROWING COTTON 



Crimson clover is the best of all cover crops 

 where the soil has been inoculated. If crimson 

 has not been grown on the farm before, only a 

 small area should be planted at first, and it 

 should be inoculated by securing soil from a 

 THREE- YEAR ROTATION 



crimson clover field and scattering it over the 

 land, at the rate of from 300 to 500 pounds per 

 acre at the time of seeding. If soil cannot 

 be secured from a crimson clover field, fairly 

 satisfactory inoculation may be obtained from 

 the nitro-culture bacteria which are prepared 

 by the U. S. Dept. of Agriculture, and also by 

 some of the leading seed houses. Unless the 

 soil has been inoculated, it will be best to plant 

 the cotton lands to rye for a winter cover crop.
