The rational fertilization of fruit trees depends somewhat 

 upon their period of growth; young trees need ample sup- 

 plies of Nitrate and potash to develop and ripen new wood. 

 Later, at the bearing age, phosphoric acid and Nitrate is 

 required for the formation of fruiting buds. These two 

 phases in the making of an orchard should have due con- 

 sideration and plant food used accordingly.
