Soil cores are processed in order to determine the amount of nitrogen, carbon and phosphorus available to plants.  The samples in this video were obtained on July 6, 2008 from a June, 2004 tundra-burn site. The soil extractor works with vacuum pressure to remove soil and salt particulates, leaving behind the clear solution for testing.
