One of the problematic outcomes of soil erosion is sedimentation in stream channels adjacent to agricultural areas. Excess sediments routinely dredged are subsequently dumped in the riparian zone, where the prolonged presence of dredged sediment piles threatens the eco-hydrological balance of the agricultural-riverine environments. Reusing dredged sediments as an amendment for adjacent agricultural fields may serve as an alternative solution. However, farmers are hesitant to use this material in their fields due to the potential for weed infestation, with the associated costs incurred by crop losses. Here, we investigate the potential for weed infestation associated with reusing dredged sediments in agriculture. The research findings validate farmers' concerns regarding the undesirable proliferation of weeds following soil amelioration with dredged sediments. We present a comprehensive protocol for assessing the necessity for weed management intervention, based on infestation potential of weeds, while specifically targeting the reduction of adverse effects caused by agricultural weeds.
