 Living roots play a pivotal role in accelerating the decomposition of dead roots in rice soils, primarily through the stimulation of microbial activity in the rhizosphere. As living roots release exudates rich in carbon and enzymes, they create biologically active microsites that promote the breakdown of recently added organic residues rather than older, more stable native soil organic matter. This “priming effect” enhances nutrient mineralization from dead roots, improving nitrogen and carbon cycling within the soil–plant system. In rice-based ecosystems, where periodic flooding and anaerobic conditions often slow decomposition, the presence of active root systems significantly boosts microbial processes and promotes more efficient turnover of fresh organic inputs. Consequently, living roots act as catalysts for residue decomposition, supporting soil fertility, nutrient availability, and overall sustainability in rice production systems.

  Organic fertilizer substitution plays a transformative role in enhancing soil health within vegetable–earthworm co-cultivation systems. Replacing a portion of chemical fertilizers with high-quality organic inputs improves soil physicochemical properties—such as nutrient availability, organic matter content, and moisture retention—creating a more balanced and resilient soil environment. The presence of earthworms further accelerates nutrient mineralization and enhances soil aggregation, resulting in improved aeration and structure. These combined practices stimulate beneficial microbial communities, increasing microbial diversity, enzymatic activities, and functional groups associated with nutrient cycling. As a result, the vegetable–earthworm co-cultivation system becomes more ecologically stable, resource-efficient, and productive, reducing environmental impacts while promoting sustainable agricultural development.

 Plant Growth-Promoting Microorganisms (PGPMs) play a crucial role in advancing sustainable agriculture by enhancing soil fertility, boosting crop productivity, and reducing reliance on chemical inputs. These beneficial microbes—including nitrogen-fixing bacteria, phosphate-solubilizing bacteria, mycorrhizal fungi, and plant growth–promoting rhizobacteria—improve nutrient availability through biological processes that convert inaccessible soil nutrients into plant-usable forms. PGPMs also stimulate plant hormone production, strengthen root architecture, and enhance stress tolerance under drought, salinity, and pathogen pressure. By improving soil structure, increasing organic matter turnover, and suppressing harmful microorganisms through natural biocontrol mechanisms, PGPMs support long-term soil health and resilient cropping systems. Their integration into modern farming reduces environmental pollution, lowers production costs, and aligns with climate-smart agricultural strategie...
