The following is our routine soil testing instructions through the University of Kentucky (also apply for UMass soil testing, with the exception of the price):

*Take multiple examples of the area to be tested, 4 to 8 inches down.

*Mix these together to equal 2 cups of soil.

*Allow to dry thoroughly.

* Put in clean baggy/container and bring to the Extension Office at 810 Barret Ave.

The test result are mailed to you (we get a copy too) with your soil’s pH and readings of major and minor nutrients along with information on how and what to change for the plants to be grown there.It takes approximately two weeks for the results to be returned.

At this time UK only tests for pH and nutrient levels. Unfortunately we do not test for heavy metals, biological contaminates or pesticides.

As some urban gardeners are worried about lead in their soil, we can help with that too. We work with the University of Massachusetts, they require 2 cups of dry soil for heavy metal and soil testing. It can be sent to them through our office. You will receive results for the level of lead in your soil, for metals, and the pH and nutrient levels. The cost of the lead testing is $17.00 with results, which are very specific, in approximately 2-3 weeks.

Feel free to contact our office if you have other questions.

Let me know if I can help you further!
