PROPER PHYSICAL CONDITION 



The fertility of the soil is developed by proper 

 tillage. The physical condition of the soil is 

 nearly always more important than mere "rich- 

 ness." A finely divided, mellow soil is more pro- 

 ductive than a hard, lumpy one of the same chemi- 

 cal composition because it retains more moisture, 

 renders plant food more available and affords 

 a more congenial and comfortable place in which 

 the plants may grow.

 unfavorable condition.
