34 FERTILISERS AS AN AID TO 



and Woburn Experimental Farm the demon- 

 strations, which extend over many 

 years, show that in each case com- 

 plete manurings with phosphates, 

 nitrogen, and potash are to be preferred. 



The heavier soils on which wheat is preferably 

 grown usually contain sufficient potash for the 

 needs of this crop, therefore a dressing of super- 

 phosphate or dissolved bone in the autumn, 

 costing about los. to 155. per acre, is all that may 

 be necessary. But if the soil is of a lighter 

 description, potash may be deficient, and it 

 would be preferable to employ about four cwts. 

 of potassic superphosphate instead. As already 

 indicated, a top dressing of nitrogenous fertiliser 

 may be advisable in the spring. 



An excellent course to adopt when a wet 

 autumn has rendered it impossible to apply the 

 fertiliser at the proper time, is to give a top 

 dressing in the early winter or spring with a
