Remember 
Legumes HOT Inoculated are ''SOIL fSOBBERS" 
—take more plant food out of soil than corn, grain or grasscrops. 
Legumes WELL Inoculated are “SO!L BUILDERS’' 
—restore, maintain and build up soil fertility. 
WHY TAKE A GAIVIBLE? 
Millions of acres of legumes have failed because 
of improper inoculation. With NITRAGIN — 
The Original Legume Inoculator, established in 
1898 — you can be sure of the most 
efficient inoculation and better results.
