Soil Testing and Plant Disease and Insect Diagnostics

Soil Testing

The University of Tennessee​ Soil, Plant, and Pest Center Lab provides soil testing for lawns, gardens, and fields. The basic test to find your soil pH and basic nutrients is $15 or $20 if you’d like for our office to help with submission. It is generally recommended to conduct a soil test every 2 – 3 years.

Soil tests can also help save money by providing suggestions to optimize soil health and improve production.  We h​ave soil test boxes, soil probe, and all necessary submission forms at our Extension office. 

Visit the Soil, Plant & Pest Center website here to learn more! 

Steps for a soil test (guide​):

  1. Gather a small shovel and a bucket
  2. Randomly select about 10 locations within/surrounding the area of interest
  3. Dig 6 inches into soil and place all locations into bucket
  4. Mix the soil evenly in bucket then place representative sample into either soil bag or box (boxes are available at the soil testing booth in front of extension office
