FERTILIZERS AND MANURES FOR THE ORCHARD 217 



veiy heavy crop, due to the treatment, may result in a de- 

 crease in the size of the individual fruits, or if a moderate 

 crop is produced the fruits may be markedly increased in 

 size. Potash appears to be of some importance in increasing 

 size. 



10. An orchard which is inter-cropped should usually 

 be manured or fertilized. 



11. So far as apple trees are concerned, the addition of 

 lime is rarely necessaiy, but it may be veiy desirable for the 

 cover- or inter-crop grown. Peach trees have occasionally 

 responded to applications of hme. 



12. Inorganic forms of artificial fertilizers seem to give 

 prompter results than the organic ones. 



13. Yield and growth go "hand in hand" and are not 

 antagonistic. 



14. An early application of nitrogen (in a quickly avail- 

 able form) will often stimulate the "set" of fruit the same 

 season and hence give immediate results.
