High-Grade Fertilizers 
Complete fertilizers are essential to all growing crops, as they supply the necessary plant food which 
may be deficient in your soil. 
of Main Plant Foods: 
The elements supplied are Nitrogen, Phosphoric Acid and Potash. Uses 
Nitrogen—Promotes leaf and stem growth, increases proportion stalk to fruit, and hastens blooming. 
An excessive amount delays maturity. 
Phosphoric Acid—Stimulates early root formation; gives vigorous start to plants; increases ratio 
fruit to stalk; improves quality of fruit and hastens maturity of crop. : 
_ Potash—Is important in sugar and starch formation; gives stiffness to stalk, helps plants to resist 
disease, and improves quality of fruit. 
Most soils furnish some of these elements and will keep plants alive, but often do not contain 
/enough food to insure a proper and healthy development. Fertilizers must be used to supply a large part 
of the missing elements.
