if it can be got, J cwt muriate of potash or 4 cwts of kainit should 

 be added; 4 cwts salt may be used instead. A sprinkling of 

 nitrate of soda may be given at the time of singling. 



In moist districts on the heavier soils the turnip crop can do 

 better without farmyard manure than either mangolds or potatoes, 

 and if there is any shortage the following may be used: 



4 to 6 cwts superphosphate or basic slag, 1 cwt sulphate 

 of ammonia, and 1 cwt sulphate of potash in the drills ; 

 1 cwt nitrate of soda as a top dressing at the time of 

 singling: no farmyard manure. 



This dressing (using basic slag and not superphosphate) would 

 also be applied where finger and toe is prevalent. It has been 

 shown that this disease is transmitted through dung; the safest 

 way of eradicating it is to lime the land, and use artificials only for 

 cruciferous crops (turnips, cabbages, etc.), which take the disease, 

 keeping the farmyard manures for cereals, grass, potatoes, man- 

 golds, etc., which do not. 



// the climate only allows 15 to 20 tons per acre it is inadvisable 

 to spend too much on manure, as the crop is hardly likely to pay 

 even for the cultivation. 



Dung will usually be necessary to hold moisture in the soil 

 for the plant: phosphates must be used on heavy land: no loss 

 need be feared, any unused material being kept safely in the soil 

 for the next crop. A small nitrogenous top dressing is desirable 

 only if the plant stands still too long in spring, and runs the risk 

 of attacks from beetles, etc. 



A suitable dressing is: 



10 loads of farmyard manure, 2 to 4 cwts superphosphate. 



Cabbages, sprouts, broccoli, etc. These crops require dung 

 almost more than any other, and in favourable situations they 

 respond also to top dressings of artificials. Those recommended for 

 mangolds may be used, but the quantity of nitrate of soda may be 

 increased according to the value of the crops up to as much as 

 10 cwts per acre in extreme cases. 



Rape and other fodder crops to be fed off by sheep. Two rules are 

 important : 



Phosphates increase the feeding value. 

 Nitrogen increases the bulk.
