the plant has taken on a pale, unhealthy look, and upon 

 the time in season, and the duration of the period of 

 drouth, depends the extent of injury to the crop. 



This is so important that it may be stated again plainly, 

 so that no reader may misunderstand. The process of 

 packing the under portion of furrow or plowed ground 

 creates five conditions to aid in carrying the growing crop 

 over long dry periods, namely: 



1. More water in the soil. 



2. A stronger capillary movement of water. 



3. More prolific growth of roots. 



4. A more rapid development of nitrates and bac- 

 teria. 



5. A larger per cent of available fertility or plant 

 elements during drouthy periods or conditions.
