A three-piece soil-sampling device was constructed to collect soil cores in polyvinyl chloride tubing to a depth of 92 cm with no or minimum contamination. The device with tube is driven into the soil with a hydraulic post-driver and removed with a chain attached to the bucket of a front-end loader on a tractor. Various depths can be sampled for analysis by cutting off proportionate sections of the tubing containing the soil core. This procedure is more rapid and poses less chance of contamination than by taking progressively deeper soil samples.
