Soil and Turf

Lawn and Garden Soil Testing, Plant Analysis and Turf grass

Hands Holding SoilGeneral Instructions:

  1. From each area to be sampled – remove any overlying mulch, compost or sod. Soil samples should be collected from the top 5-7 inches of soil. Collect approximately one cup of soil (total) with a clean trowel or shovel from four random locations (all in the area you want sampled), or ten random locations if you are using a soil probe – which you can borrow from the Extension Office.
  2. Place these four or ten soil samples collected from your area you want tested into a clean plastic container and mix them together thoroughly. Samples from different areas should not be mixed together. Remember, the sample should only contain soil and no organic matter (you want to test the soil, not the mulch or sod).
  3. Soil from each area you want analyzed should be placed in a heavy-duty plastic or soil sample bag for analysis. (You can get the soil sample bags at the Extension Office).
  4. We have copies of the Submission Forms in our office for you to fill out, otherwise you can print them off and fill them out yourself.
  5. Bring your samples (and submission form if you printed it off at home) to the Extension Office and we will take your payment (prices listed below)
  6. Once you get your results, if you would like more information you can forward them to us at uwexmail@lacrossecounty.org and our Agriculture Educator, Kaitlyn Davis, will go over them with you.
