The AgSource Labs located in Bonduel test soil samples brought into the UW-Extension office. Generally it takes seven to ten business days for the lab to process the sample and send out its findings. A copy of their findings is forwarded to the Extension horticulturalist if you require interpretive assistance. The cost is $23 per sample if you send them through the Extension office.
Instructions on how to take a soil sample:
|•||Take at least 10 soil cores and mix them together thoroughly.|
|•||Soil cores should be taken to the same depth that the roots grow. This means 5 to 7 inches for most gardens and turfgrass areas. For golf course putting greens and tees, 4 inches is more appropriate.|
|•||Place 1 to 2 cups of the well-mixed soil in a clean plastic bag or a soil testing bag from your county Extension office. Fill out the appropriate soil test form that is located on the sidebar and bring it with your payment to the UW-Extension office or directly to the soil testing laboratory.|
|Soil probes are available at a rental fee of $20. (The fee can be applied to the cost of having your soil sample processed.) Payment can be made by credit card, cash or check.|
