FAEM PRACTICE IK THE CULTIVATION OF CORN. 3 



and before planting, and also gives in detail the tillage operations 

 after planting. In addition to these tables a description is given 

 of each section studied, discussing the general conditions and cus- 

 toms found there. 



It is not improbable that tillage methods found in some sections 

 of the country could, to a greater or less extent, be profitably em- 

 ployed in other sections. In this publication, however, we are con- 

 cerned merely with setting forth the findings on actual tillage 

 methods employed by representative corn growers in the areas 

 studied, and no attempt has been made to make recommendations 

 based on the results of these studies.

GENERAL STATEMENT. 



The subject of tillage of corn can properly be divided into two 

 parts. The first bus to do with the preparation of the seed bed, 

 and the second with (lie cultivation of the growing crop. Both in 

 the preparation of the seed bed and in intertillage the prevailing con-
