amount of witch grrass present on many farms, it has been found 

 a benefit to omit the disk harrowing and substitute a good spring 

 tooth harrowing. The danger of spreading witch grass over the 

 field with the spring tooth harrow is largely exaggerated, particu- 

 larly where the presence of witch grass is used as an excuse for not 

 raising potatoes. The spring tooth harrow brings many roots to 

 the surface where they can be killed more easily. This helps to 

 reduce labor later in the season by reducing the number of weeds. 

 Having the ground in better tilth makes later operations easier, and 

 tends to increase yield. Any reduction in the amount of deep har- 

 rowing is not advisable. Simply scratching the surface is insufll- 

 cient. On clean ground three spring tooth harrowings, followed 

 by a smoothing harrow, followed immediately by the planter, have
