After taking your soil or amendment sample, (see instructions above) fill out our Testing Order Form
. Plan to ship the samples the same day you gathered them, if possible. If you must store samples until the next day, keep them refrigerated. Do not freeze your samples, as the freezing and thawing will kill many of the microbes.
Ship your soil and compost samples so they will arrive within 3-4 days at our lab. Compost teas should be shipped by next day air to our location. Send sample to: Earthfort 635 SW Western Blvd Corvallis, OR 97333.
IMPORTANT NOTE TO INTERNATIONAL CLIENTS: Complete our foreign testing order form. Also, you MUST request an official USDA PPQ Form 599 customs permit from Earthfort for your package before you ship your samples to us, and pay for shipping from your location to the USDA in San Francisco, California as well as shipping from San Francisco, California to our lab in Corvallis, Oregon. Please call our office 541-257-2612 or email us at firstname.lastname@example.org for more information. Failing to follow USDA requirements for packaging and shipping of samples can result in delays in samples arriving at our lab and fines up to $300,000 US dollars. Please call our office at 541-257-2612 if you have any question.
