172 FARMING ON FACTORY LINES 



point in the case of the mangel crop — and, finally, the 

 lifting and storing of the roots, to be considered. 



Since under my system the winter greens on the 

 mangel portion will be consumed late in spring, they 

 will be usually eaten on the land, but, in addition to 

 the manure resulting from consuming the crop where 

 grown, an additional 10 to 12 tons of dung per statute 

 acre can be applied. 



As regards artificials, mangels are very peculiar in 

 their requirements. Having been produced or bred 

 from a seaside weed, the mangel requires a good deal 

 of saJJ. A good artificial mixture for mangels 

 along with dung, consists of 4 to 6 cwt. of salt and 

 1 cwt. of nitrate of soda per statute acre. 



LIQUID MANURING FOR MANGELS 



Later on in the season liquid manure can also be 

 given to the mangels. This should not be given in 

 dry weather unless the liquid is very diluted, but it 

 may be given in damp weather undiluted. A strong 

 liquid manure applied during dry weather is liable 

 to burn the plants. If liquid manure is not available, 

 an additional cwt. of nitrate of soda should be applied 

 at discretion when the plants have got a firm hold of 

 the ground. 



If it is not possible to give as much farmyard 

 manure as the quantity mentioned above, the crop 

 should receive an additional 4 cwt. of superphosphates 

 per statute acre, as well as the quantities of salt and 

 nitrate stated. 



Sulphate of ammonia or nitrolin can be used in 

 place of nitrate of soda, but the full 2 cwt. of both 

 of these manures should be applied, mixed with the 

 superphosphate and salt, on top of the farmyard 

 manure, before the drills are closed.
