SUBSOILING, DRAINAGE, AND TILLAGE BEFORE PLOWING. 



Subsoiling is the process of breaking up or loosening the subsoil 

 without mixing it with the topsoil. This is usually done by plowing 

 a furrow with an ordinary turning plow (fig. 2) and following in 

 the bottom of this furrow with a shovel or bull-tongue plow, which 

 loosens the subsoil but does not bring it nearer the surface or mix 

 it with the topsoil. In some sec- 

 tions partial subsoiling is prac- 

 ticed by running a subsoil plow 

 in the bottom of the corn row 

 I "fore planting the corn, as is 

 the practice in Scotland County, 

 X. C, and Pike County, Ala. 

 The results of subsoiling pre- 

 sented in Table V clearly show 

 that this practice is not extensive and is usually carried on only in 

 regions which have soils low in organic matter. 



'1 In- amount of data available in regard to subsoiling is so limited 

 that no definite conclusions can lie drawn. Table Y presents a digest, 

 of the opinions of farmers concerning the effect of subsoiling on the 

 crop yield, showing the percentage of those who have practiced it, 

 the season when it is usually done, and the average depth. Opinions 

 were recorded from Borne farmers who had not practiced subsoiling.

 plement used throughout the corn-growing 

 States.
