This research develops and evaluates a Sargassum-Based Liquid Biofertilizer (SBLB) produced via anaerobic fermentation, uniquely reducing heavy metal content (e.g., arsenic from 61.6 to 4.08 mg/kg) while retaining beneficial nutrients and microorganisms. This biofertilizer was applied to banana cultivation in Dominican small-scale family farms, SBLB enhanced leaf emission (p < 0.05 in two of three farms) compared to a traditional biofertilizer (BLB) and maintained Black Sigatoka disease below intervention thresholds, matching BLB performance. Chemical and microbiological analyses confirmed SBLB’s safety and efficacy, positioning it as a sustainable alternative to chemical fertilizers. This approach mitigates Sargassum waste and supports organic farming, offering a replicable model for coastal agricultural systems.application/pdf10 páginasInglésAttribution-NonCommercial-NoDerivs 3.0 United StatesAgricultura sostenible -- República DominicanaAlgas marinasPlátano -- CultivoAlgas marinas como fertilizanteBiofertilizantesArtículo12
