Using a soil probe, take at least 10 – 12 samples six inches deep and place in a properly labeled bag. If using paper bags, make sure they will not tear easily if soil is wet. Do not mix different soil types. Tear off thatch if any is present.
Collect at least one pint of tissue (grass clippings, leaves, etc.) by hand and place in a properly labeled bag. If using a plastic bag, do not seal it. If using paper bags, make sure they will not tear easily if tissue is wet. If taking tissue samples from mower bucket, it is best to wait at least two days after sand top-dressing.
Dig into the sand pile until you reach moist or wet sand. Collect sand with moisture using a shovel or PVC pipe and place in a collection bucket. Repeat this process several times around the entire pile of sand. Dump the bucket on a clean plastic tarp and thoroughly mix the sample. Split the sample in half and continue splitting in half until a volume of one gallon is left. Place the remaining one gallon in a properly labeled plastic bag. Seal the bag tightly and double-bag if necessary before shipping. For more detailed instructions visit:
If possible, collect irrigation water samples from the irrigation system using a quick coupler. Fill a clean 12 oz. (or larger) water bottle and properly label before shipping. Bottles with preservatives are needed if testing for Nitrogen. Contact us for laboratory irrigation water bottles.
