Nitrogen 
Factories 
on your 
own farm? 
Inoculate all legume seeds just before sowing 

. . . your returns are great. 
HOFFMAN INOCULANT IS CROP INSURANCE 
Run your own nitrogen factories— 
be the owner of countless thousands of 
nitrogen factories, underground—on the 
roots of all your legume plants! Cost is 
next to nothing—upkeep nothing—no 
wages to pay—no strike troubles—yet 
your factories keep putting out nitrogen, 
paying you dividends from better 
legume crops! Plus extra dividends from 
better crops that follow on that soil. No 
business man would ever miss an op- 
portunity like that! 
Neglect of proper inoculation helps 
cause crop failures. Without bacteria to 
help get free atmospheric nitrogen, 
legume plants must depend entirely on 
the nitrogen in the soil. The nitrogen- 
gathering bacteria give any legume its 
value. Without them the plants will be 
pale and unthrifty. 
Lowest Cost Fertilizer 
One careful test showed 40 per cent 
clover, 33 per cent more soy beans, 67 
per cent more alfalfa ... actual dry 
weight, crop increases over those from 
seed not inoculated. What a bill you'd 
have to pay for enough commercial 
fertilizer to give you crop increases like 
that! Fifteen cents’ worth of inoculated 
alfalfa has returned 1,680 more pounds 
of hay to the acre. Oats following 
inoculated red clover has done twice 
as well as oats after timothy. 
Not only are yields increased by Hoff- 
man Inoculant, but also higher-quality, 
iy 
richer-protein hay is produced. Illinois 
Bulletin 349 gives data showing an 
average gain with inoculated seed of 
70.4 pounds of protein per ton of alfalfa 
hay—equal to the protein contained in 
over 400 pounds of 16% dairy feed. 
Helps Weed Control 
Hoffman Inoculant adds extra vigor to 
legumes, giving them the boost needed 
to get a head start in the race with 
weeds. Help your legumes crowd out 
the weeds—Hoffman Inoculant will 
surely help that cause along. 
Pure Live Culture 
Every can contains countless bacteria. 
Unlike chemical seed treatments, these 
bacteria are alive! Were it possible, 
wed inoculate every lot of legume seed 
in our warehouse before shipment. 
But the bacteria would not be alive 
when you were ready to sow. Inoculate 
just shortly before sowing. 
Hoffman Inoculant will produce 
nodules. Order the proper inoculant for 
the seed you're sowing. Clover inocu- 
lant is no good for alfalfa. Nor soy bean 
treatment for vetch, etc. Order for each 
seeding, even if you had inoculated that 
soil before .. . no telling what changes 
may have taken place there since. Cost 
is so low—10 cents to 20 cents per acre 
—and with returns of $20.00 to $40.00 
per acre possible—you just can’t afford 
to sow seed that’s not inoculated.
