Effects of Long-Term Application of Earthworm Bio-Organic Fertilization Technology on Soil Quality and Organo-Mineral Complex in Tea Garden

Soil quality is crucial for plant productivity and environmental sustainability. Applying bio-organic fertilizer to achieve sustainable agriculture has become popular. Tea garden soil which had been fertilized 12 years was chosen the study, microaggregate composition were studied. The results showed that earthworm treatment could increase indicators of soil’s physical chemical properties such as total carbon nitrogen in soil. Bio-organic fertilization technology significantly number activity microorganisms, upgrade enzyme related nutrients. Specifically, activities urease markedly enhanced due implication fertilizer. Additionally, SR-FTIR analysis revealed clay minerals connected nuclei with capacity bind carbon, this interaction aided by organic fertilization. replacement can improve ability iron/aluminum/silicon oxides protect aliphatic groups, polysaccharides proteins. In conclusion, continuous amendments initialize a positive feedback loop maintenance organic–mineral complex soils, contribute (SOC) storage. These confirmed feasibility improvement tea plantation ecosystems.
