Nitrogen Collecting Bacteria. 



Write to us about 

 this wonderful dis- 

 covery made by the 

 Agricultural De- 

 partment. 



THE U. S. DEPARTMENT OF AGRICULTURE SAYS: 



|'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 

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

 was not Treated, on the Right it was Inoculated Before Planting.

Immense Crops. 

 Nitro-Culture. 



Nitro-Culture is a germ, sold in dry packages like a yeast cake. 

 (Dissolve in water as per directions, which come with each package.) 



A new, sure and easy way has recently 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, cheaper — it is to 

 let nitrogen gathering germs feed the plans. 



The soil is full of air. Air is four-fifths free nitrogen. Think what 

 limitless plant food, in the form of free nitrogen, the air contains. 

 Right here the new discovery comes in. Plants can't extract nitrogen 

 from the air, but there 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. That's the secret of the new way that is making many farm- 

 ers rich. The germs do the work— the fanner gets the profit. 

 They save expense, reduce the work, increase the crop enormously, 

 even make it possible to grow Alfalfa and other crops where they 

 never would grow before. 



The new way saves the cost of fertilizers, and is v«y easy to use. 

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

 Nitro-Culture is put up in small dry packages; you can put In your 

 vestpocket. 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.

 lect the free nitrogen from the air and deposit it 

 In the soil, thus making barren land productive, 

 and after the first crop is harvested the ground 

 is left richer and better for the next year's crop.

CLOVER. 



Does your clover always make a good catch? Does it sometimes leave spots or bare places in 

 your field? Does some of it get killed out by severe winter weather? If so, inoculate the 

 seed with Nitro-Culture. 



The following table is taken from circular of the parties who furnish us with Nitro-Culture.
