The Agriculture & Gardens team wants to let you know that we are still working and available to provide guidance and help during this busy season.  While face-to-face meetings and in-person programming have been curtailed, we are still working every day to help your season be a successful one. Watch for our newsletter or visit Agriculture & Gardens to get updates on upcoming programs and newly available resources.

 

Update (4/01/2022)

The Soil Testing Service is open and accepting samples by mail only.

We have a new mailing address!  Please send all samples to the address below. Due to our relocation and construction on campus we will continue to accept samples by mail only. Please do NOT drop off a sample to the Durham campus. We apologize for this inconvenience and hope to have in-person drop off available later this summer.

*Note: If you sent your soil sample to the previous Spaulding Hall address, your sample will be forwarded to our new address and you do not need to send a new sample.

Mail all samples to: 

     UNH Extension Soil Testing Service

     34 Sage Way

     Durham, NH 03824

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

 

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 construction of our new Plant Disease Diagnostic Lab. Dr. Emran Ali, our new Director of the UNH Plant Disease Diagnostic Lab, is hard at work setting up this new space and hopes to start offering services again in June, 2022. 

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

Insect Identification Service is now open for mail-in samples only.

 For more information, and to access the submission form please visit the Insect Identification Services.
