In Pennsylvania, residents obtain a soil test through the Pennsylvania State University Extension Office, in cooperation with county extension offices. The extension office offers a basic, inexpensive soil test that analyzes the pH level and nutrient content of your soil. If you specify the plants you want to grow in your garden space, you'll even receive detailed recommendations for soil amendments, such as lime and fertilizer. Knowing your soil's soil composition saves time and money, as you know exactly which plants will flourish in your natural soil and how to adjust your soil for more finicky plants.

Preparing the Soil Sample
Determine the area of your yard you want sampled. If your starting a new vegetable garden, for example, you'll need to test that area separately from your lawn, because vegetable gardening soil requirements differ from lawn soil requirements.
Scoop eight samples from the designated area with a clean shovel. Obtain 1/2 cup of soil from each sample, digging down to a depth of at least 6 inches.
Mix the soil samples with the shovel in a clean bucket.
Pour the mixed soil onto a clean piece of paper and allow it to dry for two hours. Mix the soil again in the bucket. Scoop 1 lb. soil into the soil kit container.
Submit the Soil Test Kit
Seal the soil test kit, according to package directions.
Label the soil test kit with your name, address and an identification of the soil (for example, "vegetable garden soil").
Submit the soil test kit along with the submission form to your local county extension office.
