THE SOIL, 77 



soil when diminished to the point that crop yields are 

 limited, must be replenished. By making provision for 

 the return of organic matter we provide for the needs 

 of the plant for available plant food. It should be the 

 business of every progressive farmer to give as much 

 thought to the soil he is working as he does to his farm 

 machinery or animals. Just as his farm animals and 

 machinery fail to give good returns from bad treatment, 

 so the soil will likewise fail to produce profitably under 

 irrational treatment.
