Introduction:

Soil microbial separation funnel TULLGREN type can be used for dry extraction of soil microorganisms can also be used for wet extraction of soil microorganisms. Soil or deciduous layer samples are placed in the movable upper part of the funnel. The light and light heat caused the gradient temperature of the soil sample to be about 14°C, which promoted the downward movement of soil arthropods and similar organisms through the funnel to the collector connected to the bottom of the funnel.

The position of the lamp can be adjusted to gradually raise the soil and prevent slow-moving species from being trapped in the hard soil.

When wet extraction, the funnel is filled with water and the gauze is placed in place. Nematodes and other plankton are located at the bottom of the funnel and can be withdrawn at intervals (this method is suitable for potato nematodes). When using this method, you can use a lamp or not.
