TESTING THE SAMPLE
If growers opt to send their samples
to an extension, or a service lab it
recommends, do not delay. If possible,
deliver the sample the same day it is
collected or at least get it mailed the
same day. If there needs to be a lag
between sampling time and delivering
or mailing, keep the sample closed
and stored in a refrigerator to try and
reduce the chance of contamination.
If testing their own soil, growers
should do so immediately after
collecting the sample. When
practical, it is advisable to have the
testing materials ready to go prior to
collecting the sample.
Most DIY kits do not test the soil
itself, but rather the water that runs
through the soil. As such, distilled or
deionized water needs to be used for
irrigating the sample so that the pH
is not affected. Make sure to collect
this leachate in a clean container. At
this point, some kits test the leached
water directly, while some require
various provided chemicals added to
it (meaning growers must mix those in
and let them stand for the prescribed
amount of time).
