soda. Larger trees and greater yields have resulted. In the 

 same experiments, except in one or two cases, practically no

 phate, lime, or potash. Some indirect benefit has sometimes 

 resulted by increasing the growth of the cover crop. It is pos- 

 sible, however, that in some of the Southern peach-growing 

 regions, as Georgia and the sand hill sections of North and

Sufficient nitrate should be added to cause terminal growths 

 of 16 to 24 inches in length. If too much is added, ripening 

 may be delayed, which might be either advantageous or dis- 

 advantageous, depending upon the market conditions, and so
