672 FUNDAMENTALS OF FRUIT PRODUCTION 



impracticable at present to attempt a definition of the soil requirements 

 of different fruit plants in terms of mechanical analysis. 



Soils that are unproductive from the standpoint of cereal crops are 

 often productive from the standpoint of fruit production and the reverse 

 situation often occurs. It is even more impracticable to attempt a defini- 

 tion of the soil requirements of different fruits in terms of chemical compo- 

 sition, than in terms of mechanical analysis. The character of the vegeta- 

 tion growing naturally on a soil furnishes one of the best indices to the 

 kinds of fruit that may be expected to thrive on it. Though there are 

 indications of marked adaptation of particular varieties to certain soil 

 types, the importance of such special adaptations is often exaggerated.
