Surface (0-15 cm) soils were periodically (every 3-6 years) sampled, divided into two depth intervals, composited by sampling station and elutriated (Gross and Renner 1990) to determine seed densities, species composition, and viabilities of dominant weed species.

Weed Science 37:836-839.Data Managerhttp://lter.kbs.msu.edu/protocols/14Elutriation is a process for separating particles based on their size, shape and density. A modified version of a hydropneumatic root elutriator was used to clear seeds from soil samples and to further separate seeds by size on a series of stacked sieves with decreasing mesh sizes. See Gross and Renner (1989) for further information. Gross, K.L. and K.A. Renner. 1989. A new method for estimating seed numbers in the soil.
