Abstract

This paper assesses the likely impact of soil erosion on the composition and abundance of the arable weed seedbank, and presents an overview of erosion mechanisms affecting arable land coupled with an outline of the main factors influencing arable weed seedbank abundance and composition. The information presented on both these sets of processes enables assessment of the likely impact of soil erosion on arable seedbank biodiversity at the field and landscape scales. Seed size and shape also influence hydrodynamic behaviour through selective entrainment and preferential deposition. It is concluded that earth surface processes play an under-recognized role in structuring field-scale weed-based biodiversity in agro-ecosystems over decadal timescales
