FERTILIZERS ARE PLANT FOOD CARRIERS 
Nitrogen, referred to as Ammonia, is directly associated with the 
formation of leaves and stems in plants, promoting a quick and vigorous 
growth which is accomplished by a deep, rich green color of foliage—a 
sign of health and activity. 
Phosphorus, known as Acid Phosphate or Phosphoric Acid, hastens 
germination and favors rapid development of young seedlings, increasing 
the root growth, thus giving the young plant a good start. The forma¬ 
tion of grain and fruit begins sooner when applications of soluble phos¬ 
phorus are freely made. Phosphorus fills out the grain and fruit, in¬ 
creasing the proportion of grain to straw. 
Potassium, commonly called potash, has a marked influence upon the 
development of leaves and stems. When potash is lacking, stems are apt 
to be weak and brittle. Potash enables the plant to produce sugar and 
starch and helps to plump and fill the grain. It is also necessary irt 
developing the fleshy parts of fruit.
