GENERAL CONSIDERATIONS 



can be harvested in time to put in a late crop of 

 cotton. The roots and stubble alone will add 

 much to the fertility of the soil, but, of course, its 



full benefit as a manure is 

 only obtained when the en- 

 tire crop is plowed under. 

 As the clovers are not gener- 

 ally grown at the South most 

 Southern soils do not contain 

 the kind of bacteria that form 

 tubercles on clover roots. To 

 succeed with this crop, there- 

 fore, it is necessary in most 

 instances to resort to what is 

 known as soil inoculation, in 

 order to provide these bac- 

 teria artificially. Two meth- 

 ods of soil inoculation are 

 more or less in practical use. 

 The first consists in taking a 

 quantity of soil from a field 

 where clover of some kind 

 has already been grown suc- 

 cessfully and sowing it with 

 the seed. As much as a ton 

 of soil per acre should be used 

 to be sure of securing the 

 desired result. In the second 

 method the seeds are wet with 

 a nutritive solution to which 

 a pure culture of the desired 

 bacterium has been added some hours previously.
