Nitro-Culture 
IS NOW STRONGLY ENDORSED 
BY LEADING AGRICULTURISTS 
THE WORLD OVER 
NITRO-CULTURE is a harmless germ which increases the crop, enriches the soil andl makes poor 
farms productive by drawing nitrogen from the inexhaustible supply of the atmosphere. For a number 
of years it has been known that leguminous plants have the power to acquire this atmospheric nitrogen 
through enlargements upon the roots, called root nodules, which are caused by bacteria. Different 
crops require separate and distinct bacteria. When the soils are lacking in the proper bacteria for the 
crops which are grown upon then, it is absolutely essential that these bacteria be supplied. The farmer 
must ascertain whether or not his soil is lacking in the proper bacteria. Ifthey are already in the soil 
it is useless to add more, as no increase in yield would be obtained. If your farm will not produce good 
crops of clover or alfalfa, or if it turns yellow after once coming up; if you have tried peas and beans 
with poor results, then you may be assured NITRO-CULTURE will be of assistance to you. 
MONTVERDE, FLA., 
September 4, 1906. 
Gentlemen :—I mail you 
to-day a photograph of 
my field of Cow Peas 
treated with your Nitro- 
Culture. I am standing 
in the field with afew 
plants in each hand, in- 
oculated plants in my 
right hand and uninocu- 
lated in my left hand. 
You will see that the in- 
oculated plants are about 
twiceas high as uninocu- 
lated and are well filled 
with pods, while the un- 
{noculated are not yet in 
bloom and show not one 
nodule on their roots. 
The inoculated plants 
are full of nodules, very 
evenly distributed on all 
of the roots. My land is 
poor sand-hill land, thst 
would not make corn at 
all and very little of any 
! other crop without hay- 
ing fertilizing. These 
peas were not fertilized 
at all, and are of the 
dwarf or bush variety. 
Very truly, 
[Signed] 
GEORGE A. KIRK.

THE DIFFERENCE IN COW PEAS. (See letter alongside.) 
The bacteria are dried on absorbent cotton, which is placed in moisture-proof tubes. When diluted 
according to directions which accompany each package, the seed to be treated is thoroughly moistened 
with the solution and then put aside to dry in a shady place. Excessive heat or the direct rays of the 
sun destroy the bacteria. Before planting the seed you s:ould be sure that your soil is not sour or acid. 
If this condition should exist, it should be neutralized by a good coating of Jime, well worked into the 
soil. Where the land is of an acid nature the bacteria cannot perform their proper functions; neither 
can the crop make as good growth.
