Soil Testing, Insect ID & Plant Diagnostic Lab
Plant Diagnostic Lab & Plant Health
Update (7/14/20):
The Food and Agriculture 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 our website to get updates on upcoming programs and newly available resources.
Walk-in and mail-in samples cannot be accepted for any diagnostic service until further notice.
For home gardeners:
Please contact us at answers@unh.edu or 1-877-EXT-GROW (398-4769), photos are welcome and may help us identify any weed, disease, or insect problems you encounter. In the absence of a soil test, home gardeners are encouraged to follow guidelines recommended in our factsheets. If you have misplaced your old soil test results, contact Shyloh.Favreau@unh.edu. Soils already submitted to the UNH lab will be processed when services resume.
For commercial producers/operations only:
We are very much available to talk via phone, email, or ‘virtual’ visits. We can even make physical site visits, as long as we’re able to follow certain protocols. While we are not able to process soil samples at this time, some soil testing laboratories in nearby states are still processing; commercial growers in need of a soil test may want to consider sending samples to one of these labs. We do recommend that you make sure that they are still receiving samples prior to sending samples.
