A soil test is only effective if the sample is a good representation of the area to be tested.

For Proper Results

1. For a large lawn or garden, 15 to 20 sub-samples of soil should be taken. For a small lawn or garden, 5 to 10 sub-samples should be taken. Take sub-samples in a random or zig zag pattern.
   • Avoid road edges, next to concrete foundations, walks, etc.
   • Take samples at 4" deep for turf and 6" depth for a garden.
   
   
   
2. Mix your sub-samples together to create a 3 cup soil sample for each area you want tested.
   
   
3. Air dry the soil on paper for 24 hours (never oven dry).
   
   
4. Soil may be brought to the Extension office in a plastic bag, or any plastic or glass container. Do NOT put soil in a metal container.
   
   
5. Please DO NOT mail soil samples to the office.
