1907] Manuring of Potatoes. S5 



back to prevent unnecessary struggling, to tie the legs and hang 

 1 the bird up by them, then to stun the bird by a sharp blow on 

 the back of the head, and immediately sever the jugular vein 

 by means of a sharp penknife thrust through the neck behind 

 the lower jaw. The usual preparation for shop or market con- 

 sists of rough plucking and pressing until cold.* 



Potatoes, being worth so much more than an equal weight 

 of roots, should be more liberally treated as regards manure. 



Under ordinary circumstances farmyard 

 Manuring of manure (15 to 20 tons per acre) should 

 Potatoes. be the basis, supplemented by an arti- 



ficial manure. 



If there is abundance of organic matter in the soil, as, for 

 instance, when potatoes are taken after a two or three years 

 lea, artificials alone will, in many cases, grow a full crop of 

 potatoes. 



In view of the valuable nature of the crop, and especially 

 in the case of early potatoes, farmers can not only afford 

 to manure liberally, but it will also pay to compound more 

 omiplrx mixtures than in the ease of less valuable crop.-. 

 The following mixture, which is recommended in Leaflet 

 No. 80, will be found generally serviceable : — 



I cwt. nitrate of soda. 



1 cwt. alphate of ammonia. 



2 cwt. dissolved bones. 

 2 cwt. superphosphate. 



1 cwt. sulphate or muriate of potash (about 70 per cent, 

 purity). 



In some recent experiments carried out by the Edinburgh 

 and East of Scotland Coliege of Agriculture (Bulletin XII), 

 this mixture was tried in comparison with nine other com- 

 binations of artificial manures, and gave the best results of 

 all the mixtures tried. The substitution of nitrate of potash 

 lor nitrate of soda resulted in a slightly decreased yield.
