Abstract:
The aim of this study was to investigate the factors that influence the design of soil
engaging systems to mechanically control weeds between plants within the crop row
in widely spaced field vegetables. A mass flow soil dynamics model based on particle
dynamics was developed to aid designers in determining the lateral and forward
displacement of soil as it is undercut by shallow working wide blades. The model was
validated in soil bin laboratory experiments and used to design a novel mechanical
inter- and intra-row weeding system. Cont/d.
