40 FERTILISERS AS AN AID TO 



scarce, farmers may rely upon obtaining a 

 perfectly satisfactory crop of turnips by using 

 a lighter dressing of dung and supplementing it 

 with an application of about 4 cwt. super- 

 phosphate per acre. 



1 The results confirm those obtained in 

 previous years, and they indicate that while 

 a somewhat heavier crop may be obtained by 

 the addition of i cwt. sulphate of ammonia 

 and 3 cwt. of kainit to the standard dressing 

 of 10 tons dung and 4 cwt. superphosphate per 

 statute acre, the increased yield is produced at 

 too great a cost to be profitable. 



" As a general rule, when farm-yard manure 

 is applied to land in good condition, nitrogenous 

 and potassic manures are not required by the 

 turnip crop ; on land, however, which is naturally 

 poor, or in low condition, it is probable that 

 such manures will pay for their application.'* 

 Similar trials have been conducted in Durham, 

 by the Armstrong College, New- 

 Gu!cter castle-on-Tyne, and in Gloucester- 

 shire, under control of the County 



Director of Agriculture, and the 

 results confirm the efficacy of the method of 

 manuring just described. 



II. LARGE TURNIP CROPS WITHOUT DUNG. 



In some parts of the Kingdom, for various 

 reasons, principally that of short supply of farm- 

 yard manure, Swedes and Turnips have to be 

 grown with a very light dressing of dung, and 

 sometimes even with none at all. It is impor-
