Notes on Manures. 



of muriate of potash or 4 cwt. of kainit should be given. Most 

 farmers will use farmyard manure in addition to fertilisers for 

 their swedes owing to the importance of securing a good tilth, 

 but if there is any shortage it is better to reserve the dung for 

 the potatoes and mangolds. 



In cases where nnger-and-toe prevails basic slag should be 

 substituted for superphosphate ; lime also should be applied, 

 but dung should be omitted. It has been shown that the 

 disease can be transmitted through the dung and that the 

 organism will not nourish in well-limed soils. 



Cabbages, etc. — These leafy crops require more nitrogen 

 than almost any other crop, and in favourable situations they 

 respond to large dressings of artificials. The mixture recom- 

 mended for mangolds may be used, but the quantity of nitrate 

 of soda may be increased according to the value of the crops, 

 as much as 10 cwt. per acre being applied in certain extreme 

 cases. 



In the Bedfordshire experiments on light, sandy soil the 

 highest yield of Brussels sprouts, amounting to 696 stones per 

 acre, was given by 7 cwt. superphosphate, 1 J cwt. sulphate of 

 potash, and 4 cwt. nitrate of soda. On the heavier Oxford 

 clay the potash could be omitted, but the nitrate and phos- 

 phates were still wanted. 



In the Devon experiments with cabbages the best top dress- 

 ings were found to be f cwt. sulphate of ammonia at the time 

 of planting, then 1 cwt. nitrate of soda applied 5 weeks later. 

 Yields were : — 



Per acre. 

 Tons cwt. 



Superphosphate, kainit and salt, but no nitrogen . . 20 14J 

 Superphosphate, kainit and salt, with f cwt. sulphate 



of ammonia and 1 cwt. nitrate of soda . . . . 41 1 J 



It is not unusual to give a little nitrate a few days before 

 marketing so as to improve the colour of the crop. 



Rape and other Fodder Crops to be fed off by Sheep. — Two rules 

 are important : (1) Phosphates increase the feeding value ; 

 (2) Nitrgenous manures increase the bulk. Suitable dressings 

 are : — 



4 to 6 cwt. superphosphate or basic slag, 1 to 2 cwt. nitrate of 

 soda or sulphate of ammonia.
