Plant Food Elements 
Plants require nitrogen, phosphorus, potassium (the 
three most important), oxygen, hydrogen and carbon (ob- 
tained from air and water) and the minor elements 
usually found in the soil in sufficient quantity but also 
supplied in the better brands of mixed fertilizers. 
These minor elements are calcium, sulphur, magnesium, 
manganese, iron and boron. Their functions are largely 
indirect, but very essential as they aid the chemical 
changes which render other ingredients more available, 
Calcium (lime), for example, aids in making the nitrog- 
enous materials more quickly available and changes the 
physical nature of soils. Sulphur seems to exert a bene- 
ficial influence on plant growth and iron is necessary in 
the formation of chlorophyll. 
NITROGEN is the “top growth” element needed for 
leafy vegetables such as spinach, kale, parsley, etc. Aside 
from mixed fertilizers, nitrogen can be had in various 
organic forms as in bone meal, blood meal, tankage, fish 
meal, cottonseed meal and inorganic forms such as 
nitrate of soda (tending toward an alkaline reaction), am- 
AGRICO Fertilizers 
FOR BETTER LAWNS and GARDENS 
Each of these three special-purpose AGRICO Fertilizers 
is made to do its own job and do it better than any 
all-purpose fertilizer could possibly do. Yet Agrico costs 
no more... iS more economical to use... gives you 
more value, per pound and per dollar.

monium sulphate (tending toward an acid reaction), urea 
and potassium nitrate. The organic materials are safest 
to use as they react slowly and do not burn. 
PHOSPHORUS is generally the most needed element, 
as the continued use of manures possessing such a little 
of it, combined with the fact that most crops are heavy 
phosphorus feeders, soils worked for a number of years 
are practically depleted of this element. A real fertile 
soil is rich in readily available phosphorus, It is the 
element which promotes growth and vigor, flowers, fruit 
and seeds. Beans, corn, cucumber, tomatoes, turnips and 
rutabagas seem to respond to heavy feedings of phos- 
phorus. It is available in mixed fertilizers, superphos- 
phate, bone meal and tankage. 
POTASH is the root growing element. Asparagus, beets, 
carrots, celery, cucumbers, lettuce, potatoes and radish 
all respond to extra potash feeding. Sulphate of potash 
is best for tobacco, lettuce and leaf crops, while muriate 
of potash is most beneficial to carrots, potatoes and root 
crops.
