MANAGEMENT 57 



at least two particular groups for purposes of prac- 

 tical management. The Japanese plums should be 

 managed like peaches, while the European (domes- 

 tlca) varieties need a form of treatment more like 

 pears. They will stand rather more nitrogen than 

 pears, but the potash and phosphoric acid require- 

 ments are very much the same. This may be ex- 

 pressed roughly in the following formula : 



Nitrate of soda, 50-100 pounds 



Basic slag meal, 400-800 pounds 



High-grade sulphate of potash, 300-500 pounds 



No one knows enough of the peculiar needs of 

 quinces to justify a special formula. Quinces may 

 be treated generally after the manner of dwarf 

 apples. 



Apricots and nectarines should be treated the 

 same as peaches.
