68 CONTINUOUS CROPPING 



can be used, whereas it is difficult to operate these 

 implements after farmyard manure has been freshly 

 spread. 



On heavy land it may be an advantage to cart ana 

 plough in farmyard manure, so as to leave the soil light, 

 but by the time we have got into stride with our 

 rotation there will be plenty of humus in the soil to 

 effect this object. 



There does exist amongst farmers an idea that the 

 " sun draws the virtue out of manure *' if the latter is 

 allowed to lie on the surface, an idea which contains as 

 much truth as another axiom, now nearly obsolete, that 

 good butter could only be obtained by churning at a 

 certain phase of the moon. 



Most farmers in commencing continuous cropping 

 will probably wish to introduce a winter-green crop in 

 place of roots on land under corn last year which may 

 or may not have been growing a crop of vetches during 

 the winter for soiling in spring and early summer. 



MANURING VETCH STUBBLE 



If such an oat stubble has been uncropped during 

 the winter farmyard manure should be applied at 

 the rate of from 20 to 25 tons per statute acre, 

 together with from i to 2 cwt. of nitrate of soda when 

 the seed is sown. The same manuring may be fol- 

 lowed if a winter tare crop has been cut for hay, or 

 if the crop has been cut and carted off the land. If, 

 however, the plan of consuming the fodder crop on the 

 land has been followed, then a less quantity of dung, 

 say, about half, would suffice, and the same amount 

 of artificials. 



In case dung is not available for the crop (although 

 every attempt should be made to provide a certain 

 amount), about 4 cwt, superphosphate or, on land
