180 FARMING ON FACTORY LINES 



On loose soil or easily-tilled land, especially of a 

 peaty nature, kales, giant rape, etc., may be scattered 

 broadcast over the " nurse crop," choosing showery 

 weather for the purpose. When broadcasted, the 

 resultant crop will not grow up in rows, but when 

 the " nurse crop '• is removed, it is a simple matter 

 to run the cultivator with the tines set so as to leave 

 the crop in rows. 



The object of sowing in rows is to permit of the 

 cleaning and consequent aeration of the soil. On 

 loose soil aeration is scarcely necessary. As for 

 cleaning, the winter green crop, because it is more 

 vigorous on such land, will generally manage to 

 smother weeds.

POINTS ABOUT INTER-CROPPING 



There are one or two other points in connection 

 with inter-cropping requiring attention.
