Soil Testing Services

The soil testing lab is open!

UNH Cooperative Extension provides soil analysis and fertilizer recommendations to farmers, homeowners and researchers. Recommendations are based on the latest research and are specific to the crop being grown. 

The cost per sample varies depending upon the test you choose.

Detailed information about the many available testing options, prices, forms, and instructions for collecting and submitting your soil sample can be found on the Test Your Soil page.

Update (10/25/21)

The lab will only be accepting samples by mail until further notice. Your safety and the safety of our students, faculty and staff are our highest priority. 

Please do NOT drop off a sample to the Durham campus. For more information, and to access our soil testing forms please visit the links below. 

Turnaround time for soil testing is three weeks from the time we receive the sample(s). For questions, please send an email to Shyloh.Favreau@unh.edu or leave a message for Shyloh Favreau at (603) 862-3200
