Methods

Seed bank data estimated by direct germination. Seeds are allowed to germinate and the number of plants are counted and identified.This datatable is part of the Distribution and Composition of the Seed Bank dataset. The distribution and composition of the weed seed bank in treatments 1-7 of the LTER main site is periodically (every 3-6 years) evaluated using elutriation and seed counting methods. The goal is to determine:how well the seed bank predicts weed abundances and composition in subsequent years andhow 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. Unit of abundance = IndCountInt, Unit of biomass = NA
