FERTILIZERS FOR FRUITS 



and comparatively little growth. Ashes and muriate of pot- 

 ash are the most common sources of potash. One to two 

 tons of wood ashes, or 400 to 800 pounds of muriate of pot- 

 ash, are considered a good application per acre for bearing 

 orchards. 



Phosphoric acid is the fertilizer next in importance to pot- 

 ash, and the bone fertilizers, plain high-grade superphosphate, 

 and Thomas slag are the common sources. Three to five 

 hundred pounds is a good dressing.

Nitrogen promotes growth. Be cautious, therefore, to use 

 but little of it for fruiting plants. Sufficient nitrogen can be 

 obtained through tillage, and nitrogenous green manures. 

 Green manures apply humus to the soil and improve its 

 fertility. 



In a nut shell, fruit culture is growing fruits under rational 

 methods and giving the plants under consideration as near 

 ideal conditions as we can. Culture, adaptable varieties, 

 spraying, fertilizing, etc., must be studied, and practised if 

 we expect results.
