Seed Bank via Elutriation — Main Cropping System Experiment (MCSE)

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Number of seeds, by plant species, from soils of MCSE Treatments 1-8. Soil cores are separated into 0-5 and 5-15 cm depth intervals and plant species and seed numbers determined by elutriation of soil.

This datatable is part of the Seed Bank Distribution and Composition dataset.

This dataset contain the distribution and composition of the soil weed seed bank in Treatments 1-8 of the Main Cropping System Experiment (MCSE) at the LTER Main Site. The weed seed bank was periodically (every 3-6 years) evaluated using elutriation and germination seed counting methods. Composite soil samples to two depths were elutriated to determine seed densities, species composition, and viabilities of seven dominant target species on the site. The goal of this study was to determine:

  1. how well the seed bank predicts weed abundances and composition in subsequent years, and
  2. how changes in disturbance (tillage) and plant species (cropping systems) affect the bank.
