Nitro=Cuiture 
IS NOW STRONGLY ENDORSED 
BY LEADING AGRICULTURISTS 
THE WORLD OVER 
NITRO-CULTURE is a Harmless germ whieh increases the cro]), enriches the soil and 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. Ditl'erent 
crops require separate and distinct bacteria. "When the soils are lacking in the proper bacteria for the 
crops which are grown upon them, it is absolutely essential that these bacteria be supplied. The farmet 
must ascertain whether or not his soil is lackiim in the proper bacteria. If they 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 u]); if you have tried peas and beans 
with poor results, then you may be assured NITRO-CULTURE will be of assistance to you.

Ytai will see that tho in-

Inoouiated are not yet in

Tho inoenlated plants 
aro full of nodules, very 
t venly distributed on all 
of tho roots. My land is

would not make corn at 
all and vciy little of any

peas were not fertilized 
at all, and are of tho

Tlie 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 diy in a shady place. Excessive heat or the direct rays of the 
sun destroy the bacteria. Before planting the seed you siiould be surfj that your soil is not sour or acid. 
If this condition should exist, it should be neutralized by a good coating of lime, well worked inlfj 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.
