plant at the desired depth. The drier the region and the 

 more sandy the soil, the deeper corn may be planted. The 

 greatest danger of too deep 

 planting is that a poor 

 stand may result. 



158. Tillage After Plant- 

 ing. After the corn is 

 planted it should be har- 

 rowed once with a smooth- 

 ing harrow, or with a 

 weeder, and should be gone over again after it is well 

 up. The best time to kill weeds is when they are just 

 coming up, when they appear to be insignificant. When 



they are large enough to- 

 attract attention, they 

 are too large to be easily 

 killed. If the land is well 

 prepared and is har- 

 rowed just before plant- 

 ing, and is given these 

 two harrowings after 

 planting, it will be* well started on its way. In large fields 

 of mellow soil this work may be done with a four-horse 

 smoothing harrow that 

 will cover 16 to 20 feet, so 

 that the work may be done 

 very rapidly. On stony 

 land the weeder may be 

 used.
