The lack of necessary bacteria in the soil is often the cause of failure to secure a "catch." 
' Nitrogm" is insurance. Science has definitely shown that certain crops must have certain 
bacteria in the soill or they will prove a disappointment or a failure.

AND INCREASES THE YIELD! 
What is Fertile Soil? 
Fertile land is soil which contains plenty of plant food. 
All soils consist of finely divided rock mixed with certain 
substances which are good for plants. Then there are 
potash, phosphates and nitrogen. All these are needed 
by the plant as food, but the nitrogen is used up faster 
than the other two and is especially important. 
Why You Must Feed Your Soil 
Your growing crops are constantly taking food. They 
need this to form stalks, leaves and seed. The amount 
that is needed for an acre of average crops is very large. 
If this plant food is not put back into the land the soil 
will get poor — worn out. 
Legumes (The Partnership Plants) 
Legumes are plants which bear their seed in a pod. 
They include alfalfa, all the clovers, all peas and beans, 
cowpeas, soybeans, vetch, sweet peas and many others 
LEGUMES differ from other plants (such as corn, rye 
etc.) in that they can form a PARTNERSHIP WITH 
CERTAIN BACTERIA. When they do this the 
legume draws its nitrogen from the air — not from the 
soil. 
Why Use "NITRAGIN" Inoculator? 
To get results you must have a reliable culture. "NI- 
TRAGIN" is not a new thing. It has been tried out. 
NITRAGIN" was awarded GOLD MEDALS when 
other cultures were still unknown. The work of Nobbe 
and Hiltner, the originators of "NITRAGIN" culture 
began soon after the discovery of the Bacteria, and has 
continued until the present time. Their PAINS-TAK- 
ING, LIFE-LONG efforts have produced an inoculator 
which is uniform, easy to keep and use, and of superior 
inoculating power. "NITRAGIN" is the ORIGINAL 
PURE INOCULATOR. ^ AL 
A well inoculated legume root 
showing how "Nitragin" produces 
nodules. The simplest, safest and 
surest system of soil inoculation for 
all legumes. Awarded Gold Medal,

"NITRAGIN" bacteria 
are packed in the granular 
medium in the ventilated 
can. Don't confuse this 
with ordinary earth. The 
granular medium is the 
only substance which sup- 
plies the living bacteria 
with the right conditions 
for life. It is the nearest 
thing to their natural home. 
Its great porosity guaran- 
tees moisture and oxygen for the bacteria two 
of the vital requirements for bacteria life. Weak 
bacteria do not produce nodules. "NITRA- 
GIN" does not come on jelly medium in bottles. 
The GRANULAR MEDIUM AND VEN- 
TILATED CAN ARE SO FAR SUPERIOR 
that we have long discarded the use of bottles.
