Soil Testing Services

The soil testing service is open! Please read below for important sample submission updates.

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. 

Update (4/01/2022)

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 approximately three weeks from the time we receive the sample(s). Thank you for your patience during our busy season. For questions, please send an email to soil.testing@unh.edu or leave a message for Shyloh Favreau at (603) 862-3200.
