Sustainable utilization of dredged sediment as planting soil: field verification of nutrient supply, microbial activity, and plant growth
Yu Guanlong
IntroductionDredged sediment from inland waterway construction is often disposed of at low resource efficiency and with potential environmental risks. This study evaluates the feasibility of converting these sediments into a sustainable resource for vegetation restoration.MethodsIn a 70-day field experiment, planting soil prepared from dredged sediment amended with composted pig manure, sawdust, and composite biological agents (IS) was compared with local eucalyptus topsoil (Ctrl).
