Distribution and Composition of Seed Bank in Cropped and Successional Communities
The distribution and composition of the weed seed bank in treatments 1-7 of the main cropping system experiment (see KBS004) is periodically evaluated to determine
- how well the seed bank predicts weed abundances and composition in subsequent years, and
- how changes in disturbance (tillage) and plant species (cropping systems) affect the bank. Composite soil samples to two depths are periodically elutriated to determine seed densities, species composition, and viabilities of seven target species which are dominant on the site.
