Contact and Lab Hours

The soil testing lab is no longer open to the general public, but you may mail or drop off samples:

Mail. Most samples are mailed by USPS or other private carrier. All samples must be labeled and all orders must include a completed form listing all samples and full payment. Please see the order forms and sampling instructions at our Ordering Information and Forms page and use the mailing address below.

Drop-off. Orders may be dropped - no more than 6 samples per order - in the Drop Box on the outside of Paige Laboratory's ground floor (Google Map Directions). As with mailed samples, all Drop Box samples must be labeled and all orders must include a completed form listing each sample, and full payment. Please see the order forms and sampling instructions at our Ordering Information and Forms page. It is best to prepare your order before bringing it to campus, but forms and pens are available above the Drop Box if needed. Please note that the Drop Box cannot handle large packages, so it is necesary to limit to six samples per order, limit sample size to what is required for your analysis, and package in the least bulky way you can.

Large Order Drop-Off. If you have 30 or more samples that you would like to bring in, email kyarrows@umext.umass.edu to arrange a contactless drop-off of your order during business hours (generally 7am to 2pm).

Campus Orders. UMass Amherst departmental orders may be delivered to the lab via Campus Mail or by hand to Paige Lab with advance email confirmation of delivery instructions with kyarrows@umext.umass.edu.
