A new method for taking soil samples was devised. Vacuum is used to move the soil in an air stream from the sampling site into a sealed bag. Much of the hard, time-consuming work can be eliminated with this new method of sampling. No differences were noted in bioassay plants grown in samples of soil taken in the conventional manner, as compared to plants grown in samples taken with the vacuum device.
