SOIL TESTING FOR 
AMATEURS 
here^ what 
garden eoitors 
and writers 
SAY.- 
"More and more, American amateur gardeners, as well 
as commercial growers, are realizing that soil tests are 
needed to obtain best results with different plants. 
Formerly, the prevailing idea was to fertilize, and all 
plants received the same treatment. That explained the 
common expression of some gardeners, 'we cannot grow 
this or that plant.' The trouble being that the soil was not 
right." Edward C. Vick, 
Horticultural Editor, New York Journal-American 
"By experimenting with the reaction of different plants 
to certain foods, you can find out their requirements and 
learn to grow them to perfection," Neilson, quoted in 
"Better Homes and Gardens." 
"The owner of a soil testing kit is assured of enhanced 
standing among his fellow gardeners. He will be listened 
to with respect . . . 
Home L. Jacobs in "American Home." 
"A complete fertilizer is a balanced fertilizer only when 
it supplies to the plant the elements (nitrogen, phos¬ 
phorus, potash) which otherwise would not be present in 
sufficient quantities for normal, healthy growth . . . . 
Several systems of testing soils for the presence of avail¬ 
able plant nutrients and toxic substances have been 
developed within the last few years. Much valuable 
information may be obtained from the use of these 
systems. Tests can be made by any person who can read 
and follow directions . . . 
Dr. James Tyson, Dept, of Agronomy, Iowa State 
College, in "Gardener's Chronicle of America." 
"Each year gardeners and farmers spend millions for 
'complete' fertilizers that contain a set ration of the three 
principal plant foods—nitrogen, phosphorus and potas¬ 
sium. This gunshot application of plant foods may not 
have enough of one or too much of another chemical to 
supply the needs of the particular crop. The soil test 
shows what is present and what is lacking, and the 
grower may buy only those chemicals needed to make 
his soil highly productive. The possible economy is 
obvious . . .

Here is what our users say 
AMAZING RESULTS —We Have in our files dozens of 
letters from users who tell us of the amazing results 
they have obtained with Sudbury Soil Test Kits. Here is 
an unsolicited letter from Mr. George Thurkauf of 
Englewood, N. J.: 
"I grow exhibition dahlias. This year I cleaned up with 
them, and my success was due to your product. It was 
not a case of hit and miss when I applied my fertilizer. 
I know what my soil needed and my results have proven 
that." 
BEST INVESTMENT I EVER MADE —so says Mr. Arthur 
H. Bopp, florist and landscape architect of Cumberland, 
Md. Here is his unsolicited letter: 
"I want to say that I consider without any reserve what¬ 
soever, that the $18.50 I paid for my Soil Testing Kit was 
the best investment I ever made. Not only is the use of 
the kit so interesting, but it enables one to grow better 
stock. The main thing about it is the elimination of 
doubt, and the saving of fertilizer, which, without test¬ 
ing we may add in excess, resulting in waste and injury 
to crops. When the test so indicates, we can add only 
the deficiencies."
