Update (6/25/21)

The soil testing lab is now open for mail-in samples only.

Due to COVID-19 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 Soil Testing Services. Our staff continues to work remotely.For questions, please email soil.testing@unh.edu or leave a  message for Shyloh Favreau at (603) 862-3200.

Please mail all samples to:

UNH Cooperative Extension Soil Lab
Spaulding Hall - Room G28
38 Academic Way
Durham, NH 03824

The UNH Plant Diagnostic Lab will not be accepting samples as of June 1, 2021

As of June 1, 2021, all NH plant diagnostic samples should be sent directly to the University of Maine Plant Disease Diagnostics Lab, and not to the UNH Plant Diagnostic Lab. Please visit the University of Maine Cooperative Extension Plant Disease Diagnostic Lab website for submission forms and contact information (or visit unhpdl.org for direct links to the Maine lab, and the downloadable form).

Samples submitted to the UNH-PDL after this date may NOT be processed and cannot be forwarded to UMaine due to decomposition and loss of quality of the sample in transit).  Submitters will be requested to send new samples to the UMaine Lab.

This temporary change is necessary due to the retirement of the UNH Plant Health Specialist/Director of the UNH Plant Diagnostic Lab (Cheryl Smith). We are in the process of filling this vacancy.  

We appreciate your patience and cooperation during this time of transition, and appreciate your support for UNH Cooperative Extension.
