Enhancing Crop Productivity and Sustainability through Biological and Organic Fertilizers: Strategies for Food Security

The increasing global population demands innovative approaches to enhance food security while promoting sustainable agricultural practices. This review explores the potential of biological and organic fertilizers as effective alternatives to conventional chemical fertilizers. By examining various types of fertilizers, including biological agents such as nitrogen-fixing bacteria and organic materials like compost, the article highlights their mechanisms of action, which improve nutrient availability, enhance soil structure, and promote beneficial microbial interactions. Case studies demonstrate significant increases in crop productivity, illustrating the long-term benefits on soil health and ecosystem sustainability. Furthermore, the review addresses environmental considerations, such as reduced chemical runoff and carbon sequestration potential, emphasizing the role of these fertilizers in biodiversity conservation. However, challenges related to farmer adoption and variability in effectiveness necessitate further research and policy support. Recommendations for integrating biological and organic fertilizers into national agricultural strategies are provided to encourage sustainable practices among farmers. Ultimately, this review underscores the importance of biological and organic fertilizers in enhancing crop productivity and sustainability, contributing to global food security.
