Title : Next-generation biofertilizers and biostimulants: A microbial perspective for sustainable crop productivity.
Abstract:
Ensuring sustainable crop productivity in the 21st century demands innovative strategies that balance food security with environmental stewardship. While conventional chemical fertilizers have boosted agricultural yields, their excessive use has led to soil degradation, biodiversity loss, and climate change. In response, next-generation biofertilizers and biostimulants, especially those derived from microorganisms, are emerging as eco-friendly alternatives. Key microbial groups such as plant growth-promoting rhizobacteria (PGPR), mycorrhizal fungi, cyanobacteria, and endophytes contribute significantly to nutrient acquisition, phytohormone regulation, and enhanced tolerance against biotic and abiotic stresses. This presentation emphasizes microbial perspectives on recent advancements in biofertilizers and biostimulants, with a focus on their multifunctional roles in improving soil fertility and crop health. Notable progress includes microbial genomics, nano-formulation technologies, and advanced carrier systems that enhance inoculant stability, field efficacy, and shelf life. Furthermore, the integration of microbial consortia, synthetic biology, and precision agriculture is paving the way for tailored solutions that address crop- and region-specific requirements. By linking microbial ecology with modern biotechnology, next-generation biofertilizers and biostimulants offer a sustainable pathway to reduce reliance on chemical inputs, restore soil health, and enhance agricultural resilience. Their adoption is central to climate-smart farming practices and is poised to ensure long-term environmental and economic sustainability.
