32 CONTINUOUS CROPPING 



Now, if land is rolled in the sowing of any crop 

 when the soil is not sufficiently dry, harm is done 

 instead of good. The surface soil is made pasty and 

 when dry weather does come, the top surface of the 

 soil bakes and forms a crust, very unsuitable for plant 

 development. 



As a guide to the suitability, or otherwise, of the 

 land for rolling, remember that land is fit for rolling if 

 the soil does not stick to the roller. 



THE CORN DRILL AND THE SEED FIDDLE 



If the smallholder can obtain the use of a corn drill 

 for the sowing of the crops he should certainly do so. 

 A crop sown with the drill requires less seed, is more 

 evenly distributed, and more evenly covered in than 



The spring-tined harrow, shown here, is a necessity for 

 the economical tilling of the land. 



when broadcasted by hand or by the seed fiddle, which 

 latter implement, apart from the sowing of tares, 

 every smallholder should purchase. 



When the corn is to be drilled in, it is necessary on 

 any class of soil to harrow down the ploughed land to 

 a fine seed-bed before drilling. In connection with the 

 covering in of broadcasted seed on land which has been 

 harrowed down, and, perhaps, rolled also, it should be 

 understood that there is only one type of harrow that 

 will do this satisfactorily. That is the spring-tined 

 harrow, one of the finest inventions of the present 

 generation.
