moisture-holding soil. The soil may be too wet and may cause a rotting 

 of the young shoots as well as the conns. If the soil is too clayey the 

 shoots may not have strength enough to emerge, or they may be twisted, 

 and thus made unable to produce a good, strong spike. The following 

 data are valuable for showing the various practices and opinions as to 

 the best soil for proper growth of the plants:
