supplied that may find application in the growth of other crops 

 better adapted to conditions. The benefit of the stored moisture 

 accumulated in the soil by summer tillage or other methods is 

 usually seen in the increased growth of straw, but never has it 

 together with the rainfall been sufficient to mature the crop of grain 

 it has promised. This indicates the advisability of growing feed 

 crops which can be saved and utilized even though they do not 

 mature grain.
