For Success With Clover, Alfalfa, Cow Peas, Soy Beans, Vetch — in 



fact all legumes — you must have nitrogen. Failure with these crops is nearly 

 always due to lack of the necessary germ that helps the plant draw free nitrogen 

 from the air. The air is four-fifths nitrogen — the most expensive element of all 

 plant food. You can use this nitrogen if you grow inoculated legumes. You can 

 be sure of a good "catch," a uniform stand, of richer feeding value. 



Nitrogen gathered by the germ, or bacteria, is stored in knots, or nodules, on 

 legume roots. Part is used by the growing crop, part goes to the soil to benefit 

 succeeding crops. Experiments prove that an inoculated legume crop returns to 

 the soil an average per acre of 122 lb. yearly. This is in addition to the nitrogen 

 used by the crop itself. 



The first to appreciate the wonderful possibilities of legume bacteria were 

 Doctors Nobbe and Hiltner, of the Royal Agricultural College, of Munich, 

 Germany. For years they experimented and finally succeeded in breeding in 

 their laboratory strong, healthy, vigorous nitrogen-gathering germs. Realizing 

 that their wonderful discovery meant a world benefit only when the practical 

 farmer could make use of it. Nobbe and Hiltner evolved a way of packing the 

 germs in a medium that insured successful delivery to the farmer — the germs 

 absolutely guaranteed to be as strong, healthy and vigorous as when they left 

 the laboratory. 



This process is called the Nobbe-Hiltner Process; the product is called "Nitra- 

 gin," the trade-mark name that distinguishes the original Nobbe-Hiltner Pure 

 Culture from imitations all over the world. 



Always look for these names. If they are on the can you are getting the 

 original and the best. Don't risk your money on imitations. 



"Nitragin" Pure Culture is packed in a granular medium, in a ventilated tin 

 can. Packing date is marked on each can. The Armour Fertilizer Works posi- 

 tively guarantee the health, strength and virility of the germs for six months from 

 date of packing. 



Don't associate "Nitragin" Pure Culture with so-called liquid or jelly cultures, 

 usually packed in corked bottles. Most of these liquids or jelly cultures are still 

 at the experimental stage. It's well known that germ life and health depend on 

 air. Liquid or jelly culture, used immediately, fresh from the laboratory, often 

 give good results. But, because of the nature of the medium and its container, 

 the life of the germ is shortened; it loses strength day by day, after it leaves the 

 laboratory. Often the germs are lifeless when they reach the soil, or are too weak 

 to be of value. Direct sun rays kill or weaken bottled bacteria. The bottle 

 containing jelly culture is usually about one-quarter filled, so as to expose the 

 largest possible surface of the medium to the unfilled portion. The theory is 

 that the air contained will be sufficient to maintain. 



The Nobbe-Hiltner improved method of packing "Nitragin" Pure Culture in 

 granular form, and sending it to the farmer in ventilated tin cans, is the safe and 

 certain way. Because of this method and the nature of the medium the man- 

 ufacturers are enabled to guarantee life, strength and virility of germs for six 

 months from packing date. 



Remember, each legume requires its own particular 

 kind of bacteria. A special strain of "Nitragin" Pure 

 Culture is prepared for each legume. In ordering be 

 sure to name crop desired.

 Bulletin No. 226 



"The weight of dry matter in the inoculated crops 

 (alfalfa) amply demonstrated the culture of 'Nitragin' 

 employed for inoculation was very satisfactory for the 

 purpose for which it was intended."
