Put soil in a plastic bag and close bag tightly. When sampling for management purposes, soil should be collected over the entire field and a subsample of one pint of soil submitted to the laboratory. For a representative sample, collect the soil from 20 or more places in the sampling area. Divide large fields into sampling areas of about 10 acres each, mix together, and send one composite sample from each area. Samples should not represent more than 40 acres.
Nematodes are sensitive to heat.
Do not leave samples in the sun or other areas of high temperature. Do not allow samples to dry out. Mark the sample bag with your name and the name or number of the sampling area. Place in a mailing box. Fill out the Nematode Soil Sample Submission Form as completely as possible.
