Soil Bio-Assessment

In addressing the health of any soil, we first assess its biological quality. To get your soil to our lab, we offer two options: prepare and ship samples yourself, or we’ll pay a visit to perform all necessary sampling (fees, distance limitations may apply). Foothill Biological is always glad to offer on-site coaching (hourly rates apply). Just shoot us a request, and we’ll reserve some time.

Sampling Your Soil

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 (a square-inch will do), 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.

 

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.

 

To help ensure your microbes will have plenty of oxygen en route:

  - A sample's volume should not exceed one-third of the bag's capacity.

  - When closing the bag, leave a corner slightly open.

Choose a name for the sample (say, “orchard NW corner 1”), and write it:

  - on the bag with a permanent marker

  - on the sample submission form (link above)

Shipping your sample

Arrange samples gently in a sturdy cardboard box. If there is extra space, add packaging material to prevent jostling en route.
