Plants require nitrogen, phosphorus, potassium (the 
three most important), and minor elements. 
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, tank- 
age, fish meal, cottonseed meal and inorganic forms such 
as nitrate of soda (tending toward an alkaline reaction), 
ammonium sulphate (tending toward an acid reaction), 
urea and potassium nitrate. The organic materials are 
safest to use as they react slowly. 
AGRICO Fertilizers

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 other root crops.
