38 PRESENT-DAY GARDENING 



a fertiliser ; it should be applied in autumn to give the best 

 results. 



A second form of using concentrated fertilisers, and one 

 which serves admirably in many instances, is to mix what- 

 ever is chosen in with the manure itself prior to working it 



fr 



into the soil. One stone of kainit and two stones of super- 

 phosphate of lime, spread evenly on a thin heap of manure 

 weighing approximately one ton, and then the material 

 turned inwards and outwards two or three times to work 

 the fertilisers right through, will improve the dung by 

 somewhere about 30 per cent., and that is a consideration 

 worthy of note. 



It will be observed that nitrogen is omitted in each of 

 these suggestions, since in all soils it is far better used in 

 the spring, and in the majority of cases is best held back 

 for exclusive use as a stimulant. For spring use sulphate 

 of potash should take the place of kainit, and the quan- 

 tity must not exceed, except in the rarest circumstances, 

 3 Ibs. to the square rod. Superphosphate will also be 

 necessary, and a good dressing is 6 Ibs. to the square 

 rod. In the possible event of nitrogen being needed for 

 application early in spring, mix equal proportions of sul- 

 phate of ammonia and nitrate of soda, and use 3 Ibs. to the 

 square rod ; the mixture gives finer results than an equal 

 quantity of either used alone, and it must be forked into the 

 top 8 inches of surface soil.
