To
submit a soil sample for testing:
-Collect 300 ml
soil- (approx. 1 quart-sized zip-lock bag) from within the root zone of
the plant of concern
-Seal
the sample in a plastic bag. 'Zip-lock' or 'Whirl-pak' bags work well.
Please
do not use paper bags, they do not hold up in shipping.
-Keep
samples out of direct sunlight and cool until they can be shipped.
Ship
as soon as possible, but soil samples do not need to be overnight mailed.
