Soil Seed-Bank


Farmers, agronomists, weed and soil scientists, conservation programs, and others often want to know what kind of seeds may be present in a particular soil to prevent potential problems in today's quality-conscious markets. The soil seed-bank test can effectively identify noxious weed seed or any other seeds in a soil sample.

The soil seed-bank test was developed by the OSU Seed Laboratory. Samples are washed to remove fine clay particles, dried, then screened to separate by particle size. Seeds as small as Juncus (rush) can be retained. All particles are visually inspected by trained analysts using the high-quality microscopic Ergovision system. Seeds are removed and identified. The seeds may then be returned to the customer for follow-up studies or tested in the lab for viability.
