Samples for Sale

Soil Samples & Plant Samples

Reference samples of soil and plant remaining after program distribution are available for purchase. Pricing is below. Enrollment in the NAPT Program is not required to order samples. NAPT Primary Contacts must be logged in to receive the discount. Samples may take up to 10 days to ship from the lab.

Please double check that your request is listed in the inventory, as our system will allow you to pay for samples that are not available, which will delay your order.

Some soil samples of 1-kg size are available. Contact us if you wish to order these.

You may place your order online, or you may complete and send in a PDF by email. Please contact us at napt@soils.org if you have questions about placing an order or if you wish to pay by check or wire transfer.
