Due to its high nutrient utilization efficiency, liquid organic fertilizer has become a research hotspot in the field of agricultural planting. Artificial humic acids, which are near-nature products, can be deemed as green fertilizer, but few studies have been reported, limited their further application. In this study, artificial acids were derived from municipal sludge, and effect on rice growth, soil fertility, dissolved matter was investigated using multi-chamber root box experiments. The shoot biomass significantly enhanced by heavy metal concentration within safe limits. limit decrease pH, especially far-rhizosphere zone, improve distribution nutrients rhizosphere, near-rhizosphere, zones. use led significant electrical conductivity. carbon content zone increased, fluorescence intensity rhizosphere increased. proportion specific components just slightly changed near-rhizosphere promoted humification findings indicate that environmental impact is different conventional chemical fertilizers, they show huge potential agriculture field.
