Bearing these facts in mind, we can recom- 

 mend the following- mixtures : 



No. i No. 2 



ioo Ib. ... Sulphate of ammonia izolb. 



150 ,, ... Bone meal ... ... 200 ,, 



50 ,, ... Superphosphate ... 60 ,, 



ioo ,, ... Kainit ... ... ioo ,, 



50 ,, ... Muriate of potash ... 70 ,, 



450 Ib. per acre. 550 Ib. per acre. 



In many cases it may be found advantageous 

 to substitute 130 Ib. nitrate of soda for the 

 sulphate of ammonia in mixture No. i, and 

 1 60 Ib. in mixture No. 2. 



The first mixture is suitable for application 

 during the first three or four years, but as soon 

 as signs of the formation of nuts are observed, 

 then the second mixture should be applied, 

 in order to stimulate the trees as much as 

 possible. Where green manures have been 

 ploughed into the soil, then the quantity of 

 nitrogenous manure, especially if nitrate of 

 soda is used, can be considerably reduced. 

 These mixtures have been based on the 

 information gained from experiments on 

 orchards where the effects of the various 

 plant foods have been more or less established. 

 For instance, it has been found that the effect 

 of nitrogen is to increase the size of the fruit, 

 but in order to obtain quality as well as 

 quantity phosphate and potash must be added. 

 These play a prominent part in the formation
