How to Use Commercial Fertilizers. If fer- 

 tilizers are used, the following general rule 

 should govern: On rich lands use mainly fer- 

 tilizers that will stimulate the fruit and not 

 stalk growth. On lighter lands use more of the 

 elements to force growth, combined with others 

 which will mature the fruit. High-grade acid 

 phosphate may be considered a basis for in- 

 creasing the fruit and hastening the maturity 

 of crops. Even on the richest land it has been 

 demonstrated that a small percentage of ni- 

 trogen added to the acid phosphate gives better 

 results. 



Nitrogen. The chief function of nitrogen 

 is to promote plant growth, but it is also of very 

 great importance in the production of fruit. 

 Nitrogen enters largely into the composition of 

 plants, and it follows that everything of vege- 

 table origin is a valuable source of this sub- 

 stance. When vegetable matter is burned the 

 nitrogen is released from its combination, 

 escapes into the atmosphere, and is lost. 

 Hence, it is bad practice to burn off fields and 

 destroy vegetable matter; it is better to turn it
