Thurston Conservation District is committed to doing our part for our community and the wellness of our employees, board of supervisors, and volunteers. To continue contributing to wellness we will no longer be accepting soil samples at our District office. We ask that you send soil samples directly to A&L Western Laboratories. TCD will provide free technical assistance by analyzing and providing recommendations based on your soil and nutrient test results.

If you’re not testing, you’re guessing!

Whether you’re growing a garden, lawn, pasture, orchard, or row crops, soil testing is the best way to determine the right rate, timing, placement, and source of amendments for your particular crop and site conditions.

Thurston Conservation District assists in analyzing and providing recommendations based on your soil and nutrient test results.

It will take 2 weeks for the analysis to come back from A & L Laboratories. It is your responsibility to forward your results to our soil specialist for recommendations.

You can expect:

  • A soil analysis report from A&L Western Laboratories, which tells you the levels of each nutrient in your soil.
  • Please send this report to our soil scientist Nicole Warren
  • You will receive a write-up from Thurston Conservation District interpreting your results which will help you see whether each nutrient is high, low, and what the optimal ranges are for each nutrient.
  • Recommendations from Thurston Conservation District for how to amend your soil. These recommendations include what to apply, how much, and when based on the crop you are growing and general recommendations for our area (organic or conventional, based on preference).

Our recommendations follow land grant university guidelines and research that has been done for specific crop needs.
