PURE CULTURE 
THE SIMPLEST SAFEST AND SUREST SYSTEM 
OF SOIL INOCULATION FOR ALL LEGUMES 
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.

Last year it was used on more than a million acres. This year you should use it 
on your Clover. Alfalfa, Cow Peas, Sow Beans, Vetcli, Field Beans, Garden Peas 
and Beams—in fact on all legumes.

I ERdUSON’S NITROGEN BACTERIA 
THE MODERN WAY TO 
INCREASE CROPS AND RESTORE SOIL FERTILITY. 
’I’lie United States Department of Agriculture the Federal Re¬ 
serve Board, tlie State Departments and Colleges all advise 
"Diversify crops, grow legumes, get nitrogen into the soil.” The 
way to do this is to treat the seed with Ferguson’s Nitrogen Bacteria 
at the time of planting. Costs little, does a great deal. 
Ferguson’s Nitrogen Bacteria is of value on every kind of 
legume — including all clovers, alfalfa, peas, beans, vetch, etc. 
The bacteria draws nitrogen from the air and deposits it on the 
plant roots in the form of nitrates, available for use. It makes the 
])lant grow larger and yield more and it improves the soil. Fer¬ 
guson’s bacteria is in liquid form and the same bottle can be 
applied to any form of legume.
