Selecting Sample Locations
To examine biology in the root zone of a particular plant, sample from midway between its stem/trunk and dripline. Pull three cores from around the plant (or grouping of plants), and combine for a single sample.
To survey a broader area (pasture, crop field, garden, etc.) separate the area into zones – based on geography, prevailing conditions, variance in dominant plant type, plant health, etc. – and sample each area.
Pulling a Sample
The first thing you need is a coring tool – a large-size apple corer works well. Always collect samples when soil is moist, preferably when moisture has been present for several days. Clear any surface material from a small patch, and insert the corer. Twist and pull up, and you should have a 'core' of two to three inches. Shake it gently into a resealable plastic bag.
Choose a name for the sample (say, “orchard NW corner 1”), and write it: on the bag with a permanent marker, and on the sample submission form.


Shipping your Sample(s)
* Make sure each plastic bag is clearly labeled (using a permanent marker or affixed label on the outside of the bag) with a sample name that matches a sample name on the Order Form.
* Make sure each bag / bottle with sample material is no more than 1/3 full and has air inside to keep conditions aerobic.
* Make sure to ship your sample(s) the day of collection for same day or next day delivery. Generally, the sooner a sample arrives, the more accurate the assessment results will be.
*To help ensure prompt processing, alert us with an e-mail before shipping. For any questions, just give us a call.
