THE OLIVER PLOW BOOK 



Plowing done in this manner deeply buries all the trash in the furrow, 

 leaving a clean surface for the final preparation of the seed bed. Observe 

 the very weedy condition at the left and the entire absence of weeds pro- 

 truding between the furrow slices. It is doubly essential in deep plow- 

 ing that all the weeds be entirely covered to prevent the formation of large 

 air vents from the top of the seed bed to the bottom. 



can interfere, thus the weeds will start and provide food 

 substance for the plants. The deep fall plowing of weedy 

 ground will naturally result identically the same as the 

 spring plowing, but with this additional advantage, if 

 the ground is plowed sufficiently early in the fall and 

 enough rain falls the weeds will sprout and grow in the 

 fall and be killed by the winter's freezing.
