Microalgal biomass offers a promising biofertilizer option due to its nutrient-rich composition, adaptability, and environmental benefits. This study evaluated the potential of microalgal-based biofertilizers-microalgal Chlorella biomass, de-oiled microalgal (DMB), de-aqueous extract (DAEMB)-in enhancing lettuce growth, soil nutrient dynamics, microbial community composition. Lettuce seedlings were cultivated with these biofertilizers, plant growth parameters, photosynthetic pigments, nitrogen uptake assessed. Soil incubation experiments further examined mineralization rates, while DNA sequencing analyzed shifts in rhizosphere communities. grown biofertilizers exhibited improved parameters compared controls, achieving 31.89% increase shoot length, 27.98% root 47.33% fresh weight. Chlorophyll total chlorophyll levels increased significantly all treatments, highest concentrations observed treatment. studies revealed that DMB DAEMB provided gradual release, rapid supply. Microbial analyses bacterial fungal diversity, abundance nitrogen-fixing nutrient-cycling taxa. Notably, diversity was enriched health reducing pathogenic fungi. These findings highlight biofertilizers' enhance fertility, health, sustainable resource use agriculture.
