Did you know that the sampling process itself can be the greatest source of error in a soil testing effort?

We can help you with collecting representative samples and evaluating the profile of your soil.

For instance, we can help you design and apply a sampling protocol covering your grow area and at different depths.

The first visit is complimentary. An unlimited number of samples per visit.

Alternatively, you can provide sample(s) in a Ziploc or other air-tight container. Drop your sample(s) Mon-Fri 8:00am-5:00pm at our downtown location in Whitehorse at Northlight Innovation Hub, or at our booth at the Fireweed Market 3-7pm Thursdays May-June. You can also choose to mail it (see Contact for details).

Taking a sample

First thing to consider is the objective, i.e. what do you plan to grow? This will dictate whether you should take samples at a single depth or not, and how deep. For instance:

First depth  (in)

Second depth (in)

Berries 0-6 no need
Lettuce, melons, grass 0-6 6-12
Potatoes, corn, pumpkins 0-6 6-24
Hay grasses (e.g. brome, fesuce, pasture), alfalfa 0-12 12-24

 

Second thing to consider is representativity, i.e. how homogeneous are the conditions? This will dictate how many samples you should get analyzed. For each area that is relatively homogeneous, a composite sample can be made from which you will extract 1-2 cups to be analysed. For instance you could scoop a trowel-full of dirt from 6-10 random locations across the homogeneous area and mix that into a pail from which the 1-2 cups representative sample would be extracted. This should be repeated for each area that is relatively homogeneous.
