Are you looking to have your soil tested in your lawn, vegetable, or flower garden, non-commercial fruit crops, or for your landscape trees and shrubs? Are you looking for accurate recommendations for fertilizer applications?

Have your soil tested through Extension Brown County by the UW Soil & Forage Analysis Lab
 in Madison. A standard soil test will identify soil pH, % organic matter in the soil, and amount of phosphorus and potassium.

Step 1: Select the Sample Location
Select your sample area and remove any overlaying mulch, sod, or compost from the sample site.

Step 2: Take your Soil Sample
Collect approximately 3 - 3 1/2 cups of soil from different areas from the top 5-7 inches of soil using a clean trowel, shovel, or soil probe.

Step 3: Package your Soil Sample
Place you sample in a heavy duty plastic bag or soil sample bag. Label the bag with the sample location description, your name and contact information. 

Step 4: Bring in your Soil Sample
Bring your sample to the Extension Brown County office and staff will help you fill out a submission form.
