Correct Fertilizers Make Better Gardens 
SUDBURY SOIL TEST KIT enables you to determine the correct fertilizer to use 
for your ground. Another method is to take samples of soil from different parts of 
your yard and send to a laboratory for a test. 
Hit-or-miss gardening- methods are no longer popular with the thrifty, skillful garden¬ 
er. He is unwilling to risk good seed or good stock by planting in soil that may be un¬ 
suited to their needs. Neither does he want to buy expensive fertilizer—or to invest his 
own time and labor—until he knows by test that he is doing the right thing. 
Successful gardening is based upon a knowledge of plant requirements plus analysis 
of the soil that will make possible intelligent adjustment to plant needs. 
The Sudbury Soil Test Kits are designed to make this essential information instantly 
available to the amateur gardener. They are so simple to use that any gardener can make 
quick, practical tests that will show the acidity of his soil and any possible deficiency in 
nitrogen, phosphorus and potash. Each kit is accompanied by complete instructions and 
tables of plant needs. 
This knowledge is the gardener’s best insurance of success. It shows him the amount 
of lime, and the amount and kind of fertilizer that his plants need for strong, healthy 
growth. It also helps him to avoid the extravagant use of materials which, in excess quan¬ 
tities, will do more harm than good. 
Sudbury Soil Test Kits are used for field testing by many leading growers from coast 
to coast. They are saving money and contributing to the success of skillful amateur 
gardeners everywhere.
