NITRO=CULTURE 



T»iis new method of fertilizing soils is endorsed by the U. S. DEPARTMENT 



OF AGRICULTURE, as follows: 



THE IT. S. DEPARTMENT OF AGKICUI/TURE SATS: 

 " It is worse than useless to attempt to grow any leguminous crop without being 

 certain of the presence of the bacteria which enable the plants to fix free nitrogen. 

 Certain regions are practically devoid of the right kind of bacteria, and unless some 

 artificial means of inoculating the germs be resorted to, the crop will be a failure." 



IMMENSE CROPS WITHOUT FERTILIZERS 



A new, sure and easy way has re- 

 cently been discovered to make worn-out 

 or poor land enormously productive 

 without fertilizers and almost without 

 expense. Plants need nitrogen — can't 

 grow without it. Heretofore fertilizers 

 have been needed to put nitrogen into 

 the soil. Nitrogen is very necessary — 

 is the most expensive part of fertilizers. 

 The new way is easier, surer and 

 cheaper — it is to let nitrogen=gathering 

 germs feed the plants. 



The soil is full of air. Air is four- 

 fifths free nitrogen. Think what limit- 

 less plant food, in the form of free nitro- 

 gen, the air contains. Right here the 

 new discovery comes in. Plants can't 

 extract nitrogen from the air, but there

SEED WAS NOT TREATED ; ON THE RIGHT IT WAS 



INOCULATED BEFORE PLANTING.

are germs that can. These germs have been discovered and are 

 now being used for that purpose. 



These germs, when put into the soil, fasten themselves to the 

 roots of the plants, draw the free nitrogen out of the air, and feed 

 it to the plants. 



The new way saves the cost of fertilizers and is very easy to 

 use. The germs come ready for use, in a form called Nitro-Cul- 

 ture. Nitro-Culture is put up in small dry packages you can put 

 in your vest pocket. Simply add it to water, and sprinkle the 

 water over the seeds before planting. The germs remain on every 

 seed — live with it — increase about it — feed the roots when they 

 start and keep on feeding them. They also enrich the soil by 

 storing nitrogen in it, so that the second year's crop, whatever it 

 may be, is increased from two to ten times.
