Abstract
Sustainable agriculture focuses on maintaining the soil health, minimizing environmental impact, and promoting plant productivity. Biofertilizers, using beneficial microbes, have become a powerful tool in biofertilizer formulations, enhancing plant productivity and soil health. Microbial consortia, composed of bacteria, fungi, and algae, play a crucial role in biofertilizer formulations by improving soil health and structure, converting atmospheric nitrogen into plant-accessible forms, breaking down insoluble phosphorus, mobilizing micronutrients, and promoting plant growth through growth-regulating hormones and bio control. Benefits of microbial consortia include enhanced plant productivity, reduced environmental impact, soil health restoration and resilience to environmental stress. However, their effectiveness can be affected by factors like environmental conditions, storage and microbial species compatibility. Careful formulation and application of microbial consortia are essential for their success. Regulatory approval is crucial for large-scale implementation and understanding the interactions between different microbes is necessary to design effective consortia that maximize benefits and minimize negative outcomes. This review emphasizes the crucial role of beneficial soil microorganisms in managing the rhizosphere, promoting plant growth and yield through a cost-effective, non-toxic, and eco-friendly approach.
