deeper into the soil and thereby extends the feeding zone of 

 the root system. 



Hillsides do not wash so badly when plowed deep, since 

 the rain can sink more easily into the soil than would be the 

 case if plowed shallow. If the plowing is going to be deeper 

 than six inches, it had best be done in the fall because the 

 fall rains, aided by the freezing and thawing of winter and 

 spring, will re-establish the capillary connection with the 

 subsoil. This capillarity is necessary for a good seed bed 

 and is not so readily re-established with deep plowing as 

 where the plowing is shallow.

Plowing should not be at the same depth from year to 

 year, since such a practice does not mix the soil well and the 

 pressure of the plow and trampling of the horses will, in 

 time, solidify the bottom of the furrows. Where land has 

 been plowed four or five inches deep for a number of years, 

 we know of nothing that will make the farmer more money 

 for the added effort involved than to plow such land six or 

 seven inches deep and break up the crust. 



We plow from five to seven inches deep, depending on 

 the time of the year, the condition of the ground, and what 

 we are turning under. 



In fall plowing for corn we plow from six to seven inches,
